Answer:
The first two
Step-by-step explanation:
Do the parenthesis of the first and you will get the original equation.
Multiple the second with 4 and you will get the original equation too.
If 4/5 of the total is 48, the total can be found by dividing it by 4 and multiplying it by 5:
48/4 = 12
12*5 = 60.
