Question

Abarna drinks 1/4 litre of milk in the morning and 2/5 litre of milk at night. How much milk does she drinks every day.

Answer 1

Milk drunk in the morning=1/4 l

Milk drunk in the night=2/5 l

Total milk drunk=1/4+2/5

First take L.C.M. to make the denominators same.

L.C.M. of 4 and 5=2×2×5=20

$\large\mathtt\blue{ = > \frac{1}{4} \times \frac{5}{5} = \frac{5}{20} \:}$

$\large\mathtt\blue{ = > \frac{2}{5} \times \frac{4}{4} = \frac{8}{20} \:}$

$\large\mathtt\blue{ = > \frac{(5 + 8)}{20} \:}$

$\large\mathtt\blue{ = > \frac{13}{20} \:}$

Total milk drunk is 13/20 l
