Question

Seven-eighths of a number is 63

Answer 1

Answer:

The number is 72.

Step-by-step explanation:

Given:

Seven-eights of a number is 63.

To find the number.

Solution:

Let the unknown number be  = $x$

By the given statement :

$\frac{7}{8}\ of\ x =63$

Thus, the equation to find the number can be given as:

$\frac{7}{8}x =63$

Solving for $x$.

Multiplying both sides by 8 to remove fractions.

$8\times\frac{7}{8}x =63\times 8$

$7x =63\times 8$

Dividing both sides by 7.

$\frac{7x}{7} =\frac{63\times 8}{7}$

7 will completely divide 7 and 63.

So, we have:

$x=9\times 8$

∴ $x=72$

Thus, the unknown number = 72
