Question

find the value of each of the following dedetermines 5/-3 -2/1
plz tell step by step​

Answer 1

$\longrightarrow{\green{}}$ $\frac{5}{ - 3} - \frac{2}{1}$

Since the denominators are unequal, we cannot simply add or subtract them.

Make them equal by taking their L.C.M.

The L. C. M. of 3 and 1 is 3.

$\longrightarrow{\green{}}$ $\frac{5 \times 1}{ - 3 \times 1} - \frac{2 \times 3}{1 \times 3}$

$\longrightarrow{\green{}}$ $\frac{5}{ - 3} - \frac{6}{3}$

Seeing as the above expression has common denominators, we can now combine them.

$\longrightarrow{\green{}}$ $\frac{ - 5 - 6}{3}$

$\longrightarrow{\green{}}$ $\frac{ - 11}{3}$

$\longrightarrow{\green{}}$ $- 3.667$
