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

Answer:

Step-by-step explanation:

Let the other be $= x$

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

And one number is $\frac{3}{4}$

According to question

$\frac{3}{4} +x = \frac{7}{8}$

Subtracting $\frac{3}{4}$ from both sides we get

$\frac{3}{4} +x - \frac{3}{4} = \frac{7}{8} - \frac{3}{4}$

Taking LCM of 4 and 8 we get 8

And making

$\frac{3}{4}$ and $\frac{7}{8}$ like fraction by making denominator same.

Multiply $\frac{3}{4}$ by 2 in numerator and denominator and multiply $\frac {7}{8}$ by 1 in numerator and denominator we get

$x= \frac{7}{8} - \frac{6}{8}$

$x= \frac{7-6}{8}$

$x =\frac{1}{8}$

Hence, the other number is $\frac{1}{8}$
