Question

If four-fifth of a number is 196, then two-seventh of the same number will be ______.

Answer 1

70

Explanation:

Given,

4/5 of a number is 196.

To find,

Solution if the same number is divided by Two-seventh or 2/7

Procedure:

Let the unknown number be x

$\frac{4}{5} \times x = 196$

$x = \frac{4}{5} \div 196$

$x = \frac{5}{4} \times 196$

$x = \frac{5 \times 196}{4}$

$x = \frac{980}{4}$

$x = 245$

so, x=245

Therefore,

$\frac{2}{7} \times x$

=$\frac{2}{7} \times 245$

=$\frac{2 \times 245}{7}$

=$\frac{490}{7} = 70$

Hence, the same number when divided by 2/7 gives the solution as 70.

Hope it helps you
