Let’s solve this step by step.

First Problem:

We are given:

> 7/8 + 3/8 = ?

Since both fractions have the same denominator (8), we can just add the numerators:

7 + 3 = 10

So, 7/8 + 3/8 = 10/8

But 10/8 is an improper fraction — it’s more than 1 whole. Let’s turn it into a mixed number.

How many times does 8 go into 10? Once, with 2 left over.

So, 10/8 = 1 and 2/8

We can simplify 2/8 to 1/4 (because both 2 and 8 can be divided by 2).

So, final answer: 1 1/4

Also, the model shows that after adding, you get one full rectangle (all 8 parts colored) plus 2 extra yellow parts out of 8 — which matches 10/8 or 1 2/8 → 1 1/4.

Second Problem:

We see two models:

- First model: orange squares. There are 4 total squares, 3 are colored → so that’s 3/4
- Second model: pink squares. Also 4 total, 3 colored → so that’s 3/4

So we’re solving:
3/4 + 3/4 = ?

Add numerators: 3 + 3 = 6
Denominator stays 4 → 6/4

Again, improper fraction. Turn into mixed number.

How many times does 4 go into 6? Once, with 2 left over → 1 and 2/4

Simplify 2/4 → 1/2

So, 6/4 = 1 1/2

You could also think: 3/4 + 3/4 = 6/4 = 3/2 = 1 1/2

✔ Final Answers:

First problem:
7/8 + 3/8 = 1 1/4

Second problem:
3/4 + 3/4 = 1 1/2

Final Answer:
1 1/4 and 1 1/2
