Question

Evaluate 1/2m - 2/3n when m = 3 and n = 8

Answer 1

Given :

m = 3

n = 8

To Find :

$\frac{1}{2} m - \frac{2}{3} n$
Solution :

$\frac{1}{2} \times m - \frac{2}{3} \times n \\ \frac{1}{2} \times 3 - \frac{2}{3} \times 8 \\ \frac{3}{2} - \frac{16}{3}$
Taking their Least Common Multiple ,

2×3=6

$\frac{3}{2} \times \frac{3}{3} - \frac{16}{3} \times \frac{2}{2} \\ \frac{9}{6} - \frac{32}{6 } \\ \frac{ - 23}{6}$
The required Answer is -23/6 .

Thanks!!
