Answer:
80 or 80.3
Step-by-step explanation:
You have to find what is 55% of 146
first set up your fractions. =
for the fraction on the left the denominator is the whole amount (146) and n is the unknown number
For the fraction on the right, the numerator is where the percent goes (55) and the denominator is always 100
Next you multiply using the butterfly method
you multiply across. 146 x 55, which is 8030, and 100 x n, which is 100n,
Now divide 8030 by 100
All you have to do is move the decimal two places, since there are two zero's, and you get 80.3
When you round 80.3 you get 80
hope this helps :)
