6/7÷x=3/4
x=3/4×7/6
x=7/8

Answer 2

To Find:

By which number should three fourth of 8 upon 7 be divided to get 3 upon 4

Solution:

Let the number be x

We are supposed to find the number by which $\frac{3}{4}$ th of $\frac{8}{7}$ should be divided to get $\frac{3}{4}$

So, $\frac{3}{4} \text{th of} \frac{8}{7}=\frac{3}{4} \times \frac{8}{7}=\frac{6}{7}$

So, ATQ

$\Rightarrow \frac{\frac{6}{7}}{x}=\frac{3}{4}\\\\\Rightarrow \frac{\frac{6}{7}}{\frac{3}{4}}=x\\\\\Rightarrow \frac{\frac{6}{7}}{\frac{3}{4}}=x\\\\\Rightarrow \frac{8}{7}=x$

Hence The required number is $\frac{8}{7}$
