Answer:
18 and 72
Step-by-step explanation:
the smaller part can be assigned as x while the larger will be 4x. Both numbers need to add up to 90, giving the equation: 4x+x = 90
Solve:
4x+x = 90
5x = 90
x = 18
4x = 72
The Middle school won 17 games so the senior school won 51 games
(4-fx)/3 or (fx-4)/3 i think
Reciprocal is basically just swapping them around, so for 10/3 it's 3/10 and that's your answer!
