Question

The sum of two numbers is 7/8. One addend is 3/4. what is the other? A. 4/4 B. 1/8 C. 1/4 D. 2/8

Answer 1

7/8 - 3/4
= 7/8 - 6/8
= 1/8

answer
B. 1/8

Answer 2

Explanation:

Let the other be
`= x`

As the sum of the number is given as
`\frac {7}{8}`

And one number is
`(3)/(4)`

According to question

`(3)/(4) +x = (7)/(8)`

Subtracting
`(3)/(4)` from both sides we get

`(3)/(4) +x - (3)/(4) = (7)/(8) - (3)/(4)`

Taking LCM of 4 and 8 we get 8

And making

`(3)/(4)` and
`(7)/(8)` like fraction by making denominator same.

Multiply
`(3)/(4)` by 2 in numerator and denominator and multiply
`\frac {7}{8}` by 1 in numerator and denominator we get

`x= (7)/(8) - (6)/(8)`

`x= (7-6)/(8)`

`x =(1)/(8)`

Hence, the other number is
`(1)/(8)`
