Question

The product of 9/7 and a number is 63. Find the number​

Answer 1

Answer :-

• The other number is 49.

Given :-

• The product of 9/7 and a number is 63.

To find :-

• The other number.

Step-by-step explanation :-

• Let the number be "x".

• The product of 9/7 and x is 63.

----------------------

Hence,

$\longmapsto\sf \dfrac{9}{7} \times x = 63$

Multiplying 9/7 with x,

$\longmapsto\sf \dfrac{9x}{7} = 63$

Transposing 7 from LHS to RHS, changing it's sign,

$\longmapsto\sf9x = 63 \times 7$

Multiplying 63 with 7,

$\longmapsto\sf9x = 441$

Transposing 9 from LHS to RHS, changing it's sign,

$\longmapsto\sf x = \dfrac{441}{9}$

Dividing 441 by 9,

$\longmapsto\overline{\boxed{\sf x = 49}}$

• Hence, the other number is 49.

----------------------

Verification :-

Now to check our answer, let's multiply 9/7 with 49 and see whether their product is 63!

$\Rightarrow\tt \dfrac{9}{7} \times 49$

Reducing the numbers,

$\Rightarrow\tt \dfrac{9}{1} \times 7$

Now let's multiply the remaining numbers since we can't reduce them anymore.

$\Rightarrow\tt 9 \times 7$

Reducing the numbers,

$\Rightarrow\tt 63$

• Since the product of these two numbers is 63,

• Hence verified!
