Question

Dividing 90 in the ratio 1:2 gives ___ and 60

Answer 1

Let, the two parts be 1 and 2.
Therefore the sum of the parts = 1+2 = 3
So, if there are 3 pieces, we will divide it into 1 piece and 2 pieces.
Hence, the first part will be $\frac{1}{3}$ × 90 = 30

And the second part will be $\frac{2}{3}$ × 90 = 60
