What is the solution to the proportion #x/(12-x)=5/15#?
Solving this would require cross multiplication
we are given
on cross multiplying:
15 is taken to the L.H.S numerator and (12 - x) is taken to R.H.S numerator
so our proportion is:
note: on solving both fractions we get equal value of 0.33 on both sides thus they are in proportion as L.H.S
