let assume x percent of 150 is 39
so
150 × x % = 39
150 × x/100 = 39
x = 39×100/150 = 26 % answer
Answer:
26%
Step-by-step explanation:
In a percent proportion, the first ratio is percent/100. We do not know the percent, so we will use a variable: x/100.
The second ratio is part/whole. 39 is the part and 150 is the whole; this gives us 39/150.
This gives us the proportion
x/100 = 39/150
Cross multiply:
x(150) = 100(39)
150x = 3900
Divide both sides by 150:
150x/150 = 3900/150
x = 26
