4/5=27/x using two different methods. Explain each method
Andrei [34K]
Metathod 1
4/5=27/x
mutiply 4/5 by 27/27 and multily 27/x by 4/4
108/135=108/4x
therefor
108:135=108:4x
therefor
135=4x
divide by 4
33.75=x




metahod 2

4/5=27/x
multiply oht sides by x
4/5x=27
multiply both sides by 5/4 to clear fraction
x=135/4
x=33.75
