Question

a housewife bought 3 packets of flour but used only 2 1/4 packets. How many kilograms of flour were left if each packet contained 1/2 kg of flour?

Answer 1

3 x 1/2= 1.5

1kg has been used since 2 packets

1/2 divided by 4 = 0.125kg

1kg + 0.125kg = 1.125kg

flour left= 1.5kg-1.125kg
= 0.375kg

hence ans: 0.375kg

hope this helps :)
