A proportion is a mathematical comparison between two numbers. Often, these numbers can represent a comparison between things or people. For example, say you walked into a room full of people. You want to know how many boys there are in comparison to how many girls there are in the room. You would write that comparison in the form of a proportion.

### Proportion is a topic under which of the subjects?

• A.

Maths

• B.

Biology

• C.

Physics

• D.

Chemistry

A. Maths
Explanation
Proportion is a topic that falls under the subject of Maths. In mathematics, proportion refers to the relationship between two or more quantities that are equal or have a constant ratio. It involves comparing and relating different quantities, such as ratios, fractions, and percentages. Understanding proportions is important in various mathematical concepts, including algebra, geometry, and statistics. Therefore, it is clear that proportion is a topic studied in the subject of Maths.

### Mathematics is usually studied at .....?

• A.

Museum

• B.

Restaurant

• C.

School

• D.

Home

C. School
Explanation
Mathematics is usually studied at school because it is an academic subject that requires a structured learning environment. Schools provide the necessary resources, such as textbooks, teachers, and classrooms, to facilitate the teaching and learning of mathematics. Additionally, schools often have specialized math teachers who are trained to effectively convey mathematical concepts and guide students in their understanding and application of mathematical principles. Studying mathematics at school also allows for collaboration and interaction with peers, fostering a deeper understanding of the subject through group discussions and problem-solving activities.

### A proportion is a mathematical comparison between how many numbers?

• A.

One

• B.

Two

• C.

Three

• D.

Four

B. Two
Explanation
A proportion is a mathematical comparison between two numbers. It involves comparing the ratio of one number to another number. In a proportion, the two numbers are typically represented as fractions or ratios and are equal to each other. Therefore, the correct answer is two.

### Proportion has a relationship with which of the following?

• A.

Algebra

• B.

Indices

• C.

Percentage

• D.

LCM

A. Algebra
Explanation
Proportion has a relationship with Algebra because proportions involve comparing two ratios or fractions. In Algebra, proportions are often used to solve equations and find the value of unknown variables. By setting up a proportion, we can determine the relationship between different quantities and find the missing value. Therefore, Algebra is closely related to the concept of proportion.

### It also has a relationship with ....?

• A.

Percentage

• B.

Indices

• C.

Ratio

• D.

LCM

C. Ratio
Explanation
The concept of ratio is closely related to the given question. Ratio is a comparison of two or more quantities and it helps in understanding the relationship between them. In this context, percentage, indices, and LCM do not have a direct relationship with the question. Therefore, ratio is the most appropriate choice as it is commonly used to establish relationships between quantities.

### Only .... has to do with solving equations?

• A.

Literature

• B.

Music

• C.

Maths

• D.

Biology

C. Maths
Explanation
Maths is the only subject among the given options that primarily deals with solving equations. It involves the study of numbers, quantity, and space, and focuses on logical reasoning and problem-solving skills. In mathematics, equations are used to represent relationships between variables, and solving these equations is a fundamental aspect of the subject. Literature, music, and biology do not typically involve solving equations as a central component of their study.

### Mathematical proportions are often used by ..... to compare information.

• A.

Drivers

• B.

Hunters

• C.

Artistes

• D.

Scientists

D. Scientists
Explanation
Mathematical proportions are often used by scientists to compare information. Scientists use proportions to analyze data and make comparisons between different variables. Proportions allow them to determine relationships and patterns, and draw conclusions based on the data they have collected. By using mathematical proportions, scientists can make accurate and reliable comparisons, which are essential in their research and investigations.

### You can tell if ..... fractions are proportional by using cross multiplication.

• A.

One

• B.

Two

• C.

Three

• D.

Four

B. Two
Explanation
To determine if two fractions are proportional, cross multiplication can be used. This involves multiplying the numerator of the first fraction by the denominator of the second fraction, and then multiplying the numerator of the second fraction by the denominator of the first fraction. If the two products are equal, then the fractions are proportional. This method helps in comparing the relative sizes of fractions and identifying if they have the same ratio or proportion.

### Who among these men is a not a scientist?

• A.

Albert Einstein

• B.

Wole Soyinka

• C.

Isaac Newton

• D.

Bill Nye

B. Wole Soyinka
Explanation
Wole Soyinka is not a scientist. He is a renowned Nigerian playwright, poet, and essayist. He was awarded the Nobel Prize in Literature in 1986, making him the first African laureate. While Albert Einstein, Isaac Newton, and Bill Nye are all well-known scientists in their respective fields, Wole Soyinka has made significant contributions to literature and the arts rather than scientific research or discoveries.

### How many equal fractions does it take make a proportion?

• A.

One

• B.

Two

• C.

Three

• D.

Four

B. Two
Explanation
A proportion is a statement that two ratios are equal. In order to form a proportion, we need two equal fractions. If we only have one fraction, we cannot compare it to anything and determine if it is proportional or not. Therefore, it takes two equal fractions to make a proportion.
