Question

7/10 + 1/2 Find sum in simplest form

Answer 1

Hello there!

Here, you simply need to make sure both fractions have common denominators!

Denominator = bottom number

10 and 2 are denominators!

So, let's look at them. 10 is not the same as 2.

The ONLY way to make them the same is multiplication.

So, since 10 is the bigger number, we'll leave it alone. Let's look at 2.

Can 2 become 10? Yes! How? Multiply 2 by 5!

2 x 5 = 10

Now let's look at the fraction!

1/2 --> ?/10

If we multiplied 2 by 5, then we also have to multiply 1 by 5!

1/2 --> 5/10

So now you've got:

7/10 + 5/10

Add the numerators (top numbers) together.

7+5 = 12

When adding/subtracting, the denominators always stay the same!

12/10 = your (unsimplified) answer.

Now we have to simplify it. How? Divide the top and bottom by 2!

12/2 = 6
10/2 = 5

So your simplified answer would be 6/5 !

Hope this helped!
