Answer: The proportion is 9/w = 25/100
Step-by-step explanation:
Solve by cross multiplying
9 × 100 = 25 × w
900 = 25w . Divide both sides by 25
900/25 = 25w/25
36 = w
It is also possible to use simpler fractions if you remember that 25% is the same as 1/4
9 is 1/4 of w,
9 = w/4 So multiply both sides by 4
4(9) = 4(w/4) . The 4s "cancel" on the right
36 = w
