1.
1/4" is the same as 2/8.
Correct Answer
A. True
Explanation
The statement is true because both 1/4 and 2/8 represent the same fraction, which is one-fourth. When we simplify 2/8, we can divide both the numerator and denominator by 2 to get 1/4. Therefore, 1/4 is indeed the same as 2/8.
2.
5/8" is the same as 10/16".
Correct Answer
A. True
Explanation
The statement is true because both 5/8" and 10/16" represent the same fraction. By simplifying 10/16", we can divide both the numerator and denominator by 2 to get 5/8". Therefore, 5/8" is indeed equivalent to 10/16".
3.
16/16" is the same as 2"
Correct Answer
B. False
Explanation
The statement "16/16" is the same as "2" is false. When we simplify the fraction 16/16, we can divide both the numerator and denominator by 16, resulting in 1/1. Therefore, 16/16 is equal to 1, not 2.
4.
1-5/8" is the same as 11/8"
Correct Answer
B. False
Explanation
The statement is false because 1-5/8" is not the same as 11/8". 1-5/8" is a mixed number, which means it represents a whole number (1) and a fraction (5/8). On the other hand, 11/8" is an improper fraction, which means the numerator (11) is greater than the denominator (8). Therefore, these two measurements are not equal.
5.
There are 4, 16ths in a quarter inch.
Correct Answer
A. True
Explanation
There are 4, 16ths in a quarter inch because a quarter inch can be divided into 16 equal parts, and each of these parts is called a 16th. Therefore, there are 4 of these 16ths in a quarter inch.
6.
How man sixteenths in 9/16" over a half inch?
Correct Answer
one, 1
Explanation
There is one sixteenth in 9/16" over a half inch. This can be determined by dividing the total length of 9/16" by the length of a sixteenth, which is equal to 1/16". Since 9 divided by 1 is equal to 9, it means that there are 9 sixteenths in 9/16". However, the question specifically asks for the number of sixteenths over a half inch, which is equal to 8 sixteenths. Therefore, the correct answer is one, or 1.
7.
How many sixteenths are in One quarter of an inch?
Correct Answer
4, four
Explanation
One quarter of an inch is equal to 4 sixteenths. This is because there are 16 sixteenths in one inch, so dividing one inch into four equal parts gives us 4 sixteenths in each quarter. Therefore, one quarter of an inch is equal to 4 sixteenths.
8.
How many eighths are in an inch?
Correct Answer
8, eight
Explanation
There are 8 eighths in an inch because an inch can be divided into 8 equal parts, each part being one eighth of an inch. Therefore, when measuring or dividing something in inches, it is possible to have 8 eighths in total.
9.
How many sixteenths are in 3/8 of an inch?
Correct Answer
6, six
Explanation
To find out how many sixteenths are in 3/8 of an inch, we need to determine how many sixteenths make up 3/8. Since there are 16 sixteenths in one whole, we can divide 3/8 by 1/16 to find the answer. When we divide 3 by 1, we get 3. And when we divide 8 by 16, we get 1/2. Therefore, 3/8 is equal to 3/2 sixteenths, which simplifies to 6 sixteenths.
10.
The decimal for 9/16 is _________
Correct Answer
.562
Explanation
The decimal for 9/16 is .562 because when you divide 9 by 16, you get 0.5625. However, since the question asks for the decimal, you round down to the nearest thousandth, which is .562.
11.
The decimal for 1/16 is ___________
Correct Answer
.062
Explanation
The decimal for 1/16 is .062 because when we divide 1 by 16, we get a quotient of 0.0625. Since the question asks for the decimal, we round the quotient to the nearest thousandth, which is .062.

It takes _______ sixteenths to equal an inch?
Correct Answer
B. 16
Explanation
An inch is divided into 16 equal parts called sixteenths. Therefore, it takes 16 sixteenths to equal an inch.

What is the average distance travelled by the balloons in this experiment?remember to correctly label your answers (s, mm, cm, m, etc)
Correct Answer
7.109m, 7.109 m, 7.109 meters, 7.11m, 7.11 m, 7.11 meters
Explanation
The average distance traveled by the balloons in this experiment is 7.109 meters or 7.11 meters.
18.
Ok, lets say that each balloon in this experiment was a different size and a different shape. Looking at the data, tell me which balloon probably had the least amount of drag AND why you think so. Also, which balloon probably had the most amount of drag AND why you think so.
