Question

what number should be added to 4/54 to get 13/15​

Answer 1

Answer:

106/135 should be added to 4/54 to get 13/15 .

Step-by-step explanation:

Let the number to be added be x .

According to the question,

$\frac{4}{54} + x = \frac{13}{15} \\ = > \frac{2}{27} + x = \frac{13}{15} \\ = > x = \frac{13}{15} - \frac{2}{27} \\ = > x = \frac{117 - 10}{135} \\ = > x = \frac{106}{135}$

Answer 2

$Let \: the \: second \: number \: be \: x.$

$\frac{4}{54} + x = \frac{13}{15}$

$x = \frac{13}{15} - \frac{4}{54}$

$x = \frac{13}{15} \times \frac{18}{18} - \frac{4}{54} \times \frac{4}{4}$

$x = \frac{234 - 16}{270}$

$x = \frac{218}{270}$

$x = \frac{109}{135}$
