Question

Sarita had $\frac{8}{10}kg.$ of sweet. She gave $\frac{1}{2}$ of this to Radha. How many kg. of sweet is left for ?

Answer 1

Sarita had $\frac{8}{10}$kg of sweet

$\frac{8}{10}$ of a kilogram$=\frac{8}{10}\times 1000$gms$=800$gms

Sarita gave $\frac{1}{2}$ of this to Radha$=\frac{1}{2}\times 800=400$gms

Sweets leftover with Sarita$=800-400=400$gms

$1000$gms$=1$kg

$\Rightarrow 400$gms$=\frac{400}{1000}=\frac{2}{5}$kg

$\therefore$ Sweets left over with Sarita is $\frac{2}{5}$kg.
