Question

subract -6/21 from 5/63​

Answer 1

In context to question asked,

We have to determine the number when $-\frac{6}{21}$ is subtracted from $\frac{5}{63}$

For determining the value of required number,

We will determine the LCM of both the denominator of the fractions.

So, we will get,

LCM of 21 and 63 will be 63.

So, now multiplying both numerator and denominator by 3.

We will get,

$\frac{5}{63} - (-\frac{6\times 3}{21\times 3})\\=>\frac{5}{63} +\frac{18}{63})\\=>\frac{23}{63}$

Hence, we will get $\frac{23}{63}$  when the number when $-\frac{6}{21}$ is subtracted from $\frac{5}{63}$.
