Question

Write the number in the box `square` such that `3/7 xx square = 15/98`

Answer 1

Let the missing number be x.

Then, `3/7 xx x = 15/98`

`\implies` x = `15/98 ÷ 3/7 = 15/98 xx 7/3`  ...`[∵ "Reciprocal of"  3/7 = 7/3]`

x = `5/14`

Hence, \[\frac{3}{7} \times \frac{\boxed{5}}{\boxed{14}} = \frac{15}{98}\]
