Question

Mary has 3/8 of a medium pizza left .Héctor has 2/8 of another médium pizza left . how much pizza do they have altogether

Answer 1

Answer:

5/8

Step-by-step explanation:

How much pizza is left between Mary and Hector combined?

Since both had a medium pizza, we'll say the pizzas were the same size.

So, we just have to make the sum:

$\frac{3}{8} + \frac{2}{8} = \frac{5}{8}$

The addition is easy since both members of the addition have the same denominator (8).  So, we just have to add up the numerators.

Since 5/8 is already expressed to its most simple expression, that's the answer.

Answer 2

Hello!

The answer is:

$\frac{5}{8}$  

Why?

Let's make an equation to calculate how much pizza do they have altogether.

Let Mary be "x" and Héctor be "y".

So, since we need to calculate how much pizza do they have, let's write the following equation:

$x+y=Pizza$

Where,

$x=\frac{3}{8}\\\\y=\frac{2}{8}$

Then, substituting into the equation, we have:

$\frac{3}{8}+\frac{2}{8}=Pizza\\\\Pizza=\frac{3}{8}+\frac{2}{8}$

Now, since both fractions have the same denominator (8), we can add the numerators, so:

$Pizza=\frac{3+2}{8}=\frac{5}{8}$

Hence,

Mary and Héctor have $\frac{5}{8}$ of a medium altogether.

Have a nice day!
