Answers

Answered by pentes124

The total cost is considered as one unit, 1. So, if Albert pays 3/7 of 1, then, Robert must pay 1-3/7, i.e, 4/7. So, Robert pays 4/7 of the total cost

gunisoni: i don't understand

pentes124: what do you don't understand?

gunisoni: whole question

pentes124: It's easy, the amounts paid by both friends are fractions of the total cost. So their sum must be 1

LET ROBERT PAYS x.
Then
x+3\7 = 1
x = 1- 3/7
=4/7
