Question

3/7 x ? = 15/98
class 7​

Answer 1

Given:

• $\tt{ \frac{3}{7} \times ? = \frac{15}{98} }$

To find:

• Value in ques. mark

Solution:

Let take it x

$\large \tt \frac{3}{7} \times x = \frac{15}{98}$

$\large \tt x= \frac{15}{98} \div \frac{3}{7}$

$\large \tt x= \frac{15}{98} \times \frac{7}{3}$

$\large \tt x= \cancel \frac{15}{98} \times \cancel \frac{7}{3}$

$\large \tt x= \frac{5}{98} \times \frac{7}{1}$

$\large \tt x= \frac{5}{98} \times {7}$

$\large \tt x= \frac{5 \times 7}{98}$

$\underline{ \boxed{\tt x= \frac{35}{98} }} \pink\bigstar$

Verification:

• Put the value of x

$\large \tt \frac{3}{7} \times \frac{35}{98} = \frac{15}{98}$

$\large \tt \cancel \frac{3}{7} \times \cancel\frac{35}{98} = \frac{15}{95}$

$\large \tt \frac{3}{1} \times \frac{5}{98} = \frac{15}{98}$

$\large \tt \frac{3 \times 5}{1 \times 98} = \frac{15}{98}$

$\underline {\boxed{\tt \frac{15}{ 98} = \frac{15}{98}} } \blue\bigstar$

• Hence, Verified
