Question

Four friends had pizza at a party. Stacy ate 1/3 of a pizza. Alexa had 1/2. Tenaya had 3/8. Natalie had 4/6. Which friend ate the least amount of pizza?

Answer 1

Answer:

Stacy ate the least amount of pizza.

Step-by-step explanation:

Since each friend ate different fractions of pizza, in order to compare them, you would need to find a common denominator for all of the fractions.  To find the common denominator, you need to find the least common multiple (LCM) of all four numbers: 3, 2, 8 and 6.  The LCM would be 24.  Now, convert all of the fractions to a denominator of 24 by multiplying the numerator and denominator by the same factor:

Stacy: $\frac{1}{3} = \frac{8}{24}$

Alexa: $\frac{1}{2} = \frac{12}{24}$

Tenaya: $\frac{3}{8} = \frac{9}{24}$

Natalie: $\frac{4}{6} = \frac{16}{24}$

Since Stacy only had 8/24, or the lowest numerator of '8', then she ate the least amount of pizza.
