Step-by-step explanation:
What is 50 percent of 150? = 75.
Answer:
If you think of it logically, this problem is saying:
x ⋅ 1 % = 39
1 % is 1/100 so it's
x ⋅ 1/100 = 39
Divide both sides by 1/100 and you get
x = 39/1/100
Remember that when there is a fraction in the denominator we flip it and multiply that on top and bottom:
x = 39 ⋅ 100 (1/100) ⋅ 100
Therefore
x = 3900
You can check this by multiplying our answer by 1 %
3900 ⋅ 0.01 = 39
Answer:
100

440 + s = 540
s = 100
