To find out how many mangoes Sade had, we need to determine the share of mangos allocated to Sade in the given ratio.
Let's denote the share of mangos allocated to Chinwe, Dat, and Sade as C, D, and S, respectively.
The given ratio is 1:2:3, which means that the share of mangos allocated to Sade is 3 parts out of a total of 1+2+3=6 parts.
To find the share of mangos allocated to Sade, we calculate:
S = (3/6) * 150
Simplifying this expression, we get:
S = (1/2) * 150
S = 75
Therefore, Sade has 75 mangoes.
