Answer:
60 . 50% of 60 is 30
Step-by-step explanation:
50% of something = 30 this means that half of something is equal to 30. This can be found by multiplying 30 by 2. The answer would be 60.
This can also be found using algebebra
50% X x = 30
convert 50% to decimal
(50% = 50/100=0.5)
0.5 X x = 30
Multiply both sides by 2 to make the 0.5 equal to one so that x is isolated.
x=60
