3/9 cannot be simplified.
Correct Answer
B. False
Explanation
The given statement is false because 3/9 can be simplified. Both the numerator and denominator have a common factor of 3, so we can divide both by 3 to simplify the fraction. After simplifying, we get 1/3, which is the simplest form of 3/9.
6.
3/4 is the lowest term of 6/12.
Correct Answer
B. False
Explanation
The statement is false because 3/4 is not the lowest term of 6/12. To find the lowest term of a fraction, we need to simplify it by dividing both the numerator and denominator by their greatest common divisor. In this case, the greatest common divisor of 6 and 12 is 6. Dividing both the numerator and denominator of 6/12 by 6 gives us 1/2, which is the lowest term of the fraction.
7.
Which of the following will help reduce fractions into lowest terms?
Correct Answer
A. Divide the numerator and denominator by their GCF
Explanation
Dividing the numerator and denominator by their greatest common factor (GCF) will help reduce fractions into lowest terms. The GCF is the largest number that divides both the numerator and denominator without leaving a remainder. By dividing both the numerator and denominator by their GCF, we can simplify the fraction and express it in its lowest terms. This process ensures that the fraction cannot be further simplified and is in its simplest form.
8.
Which of the following is in the simplest form?
Correct Answer
A. 5/6
Explanation
The fraction 5/6 is in the simplest form because the numerator (5) and the denominator (6) have no common factors other than 1. This means that the fraction cannot be further reduced or simplified.
9.
Which of the following is the lowest term for 5/55?
Correct Answer
A. 1/11
Explanation
The lowest term for a fraction is when the numerator and denominator have no common factors other than 1. In this case, the numerator 5 and the denominator 55 have a common factor of 5. By dividing both the numerator and denominator by 5, we get the fraction 1/11, which is the lowest term for 5/55.
10.
Which of the following is equivalent to 3/12?
Correct Answer
A. 1/4
Explanation
The fraction 3/12 can be simplified by dividing both the numerator and denominator by their greatest common divisor, which is 3. When we divide 3 by 3, we get 1, and when we divide 12 by 3, we get 4. Therefore, the equivalent fraction of 3/12 is 1/4.
