Question

write as a single fraction
1 - 2/p - 3/t​

Answer 1

Given: Given expression is 1 - 2/p - 3/t.

To find: We have to convert it to a single fraction.

Solution:

The given expression is 1 - 2/p - 3/t.

To convert it in a single fraction we have to make a LCM of below functions.

$1 - \frac{2}{p} - \frac{3}{t}$

LCM of p and t is pt.

Multiplying and dividing the whole expression with pt we get-

$(1 \times pt - \frac{2}{p} \times pt - \frac{3}{t} \times pt ) \div pt \\ = \frac{(pt - 2t - 3p)}{pt}$

The simplified fraction is

$\frac{(pt - 2t - 3p)}{pt}$
