( please explain it to me!) 7. Wei's mark on a test was 39. This
Maurinko [17]

Answer:

65

Step-by-step explanation:

Since 39 is equal to 60%, and 60% is also equal to 60/100, then 39/x (x is the total we are solving for) is equal to 60/100.

Cross multiply so 39/x = 60/100

39*100 = 60x

3900 = 60x (divide both sides by 60)

65 = x
