Question

what no. should be added to 4/54 to get 13/15​

Answer 1

4/54 + x = 13/15

x = 13/15 - 4/54

LCM = 270

x = 104 - 20 / 270

x = 84 / 270

x = 42/135

x = 14 / 45

Hope it helps you friend!

Answer 2

Step-by-step explanation:

Let that number be X.

according to the question -

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

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

$15(4 + 54x) = 13 \times 54$

$60 + 810x = 702$

$810x = 702 -60$

$810x = 642$

$x = \frac{642}{810}$

$x = \frac{107}{135}$
