Can somebody plz me im struggling on it.

1. - 1/8

First you take the 7/16 out of the parentheses and since there is an ➕ infro t of it the equation stays the same. So it would look like this:

5/16 - 7/16

Then subtract the fractions to get -1/8

2. 1/3

Remove the parentheses to get 3/5 - 4/15 then subtract the fractions to get your answer, 1/3

3. -3/2

First use the greatest common divisor by 3 and reduce the numbers so your equation will look like this:

- 7/2 ➕ 2

Then calculate the sum to get your -3/2

4. 4.3

First remove the -1.3 from the parentheses and it would look like this: 5.6 - 1.3 then subtract to get your 4.3

5. -2.8

Add the  two numbers together to get your -2.8

6. -5.61

Remove the parentheses so your equation looks like this: 7.15- 12.76 then subtract them to get your -5.61

Hope this helps! :3

1)is not similar since corresponding sides are not in the same ratio

2)are similar since corresponding sides are in the same ratio and corresponding angles are equal

hope it will
