Question

10 13 ? start fraction, 13, divided by, 10, end fraction of a number is what percentage of that number?

Answer 1

Answer:

130%

Step-by-step explanation:

Let x be the unknown number.

$\frac{13}{10}$ of the unknown number = $\frac{13}{10}x=1.3x$

We need to find the $\frac{13}{10}$ of a number is what percent of that number.

$\%=\frac{\text{New value}}{\text{Initial value}}\times 100$

Substitute 1.3x for new value and x for initial value in the above formula.

$\%=\frac{1.3x}{x}\times 100$

Cancel out the common factors.

$\%=1.3\times 100$

$\%=130$

Therefore, $\frac{13}{10}$ of a number is 130% of that number.
