Question

Expand -2a(5b-3) Dayo and bunmi share a certain amount in the ratio 2:3 respectively. If dayo share is #120, find the amount

Answer 1

N300

Explanation:

Given data

1. Expand -2a(5b-3)

open bracket

=-2a*5b + 2a*3

=10ab+3a

2. combined ratio= 2+3= 5

Dayo's share is #120

let us apply the part to all approach

2/5=120/x

cross multiply

120*5= 2x

600=2x

x= N300

Hence the amount is N300
