Question

Subtract. ​ 7/8-(-3/8) ​ Enter your answer in the box as a fraction in simplest form?

I'm confused tbh i don't know if i'm suppose to subtract or add but i looked up an example like 10-(-3) and it added to 13

But answer for addition is 1 and 1/4
And subtraction is 4/8 and and the simplest form is 1/2 please help!

Answer 1

The answer is negative 1 1/4 

Answer 2

Simple....

so you have:
`(7)/(8)-(- (3)/(8) )`

There's the law where if the number outside your parentheses is negative along with the number in the parentheses; it converts into positive...

-->>x-(-x)
--->>x+(+x)

This being said.....


`(7)/(8) - (-(3)/(8) )`

-->>
`(7)/(8) +(+ (3)/(8) )`

-->>>
`(10)/(8)`

But remember, you want to simplify it....


`(10)/(8) = (5)/(4)` (Decimal form..1.25)

Thus, your answer.
