Question

Michael ran 450 miles this month preparing for a race. 40% of the miles

he ran were during bad weather. How many miles did he run during bad
weather?

Answer 1

180 miles

Explanation:

You must find 40% of 450 and you can make the of into an x (multiplication symbol) like so:

40% x 450

Now, percent's are fractions, and 100% is equal to one whole or 1. To make 40% a fraction, simply just place a decimal in front of the 4, like so:

.40 or 0.40 or 0.4 or .4

Now place that in the equation:

0.40 x 450

Solve:

450.00

x 0.40

___________

180.00

^

(!Important! !Always bring down the decimal in the exact place it was at in first place!)

Check:

180 = 40%

450 = 100%

(To get 450 you must multiply 100 by 4.5, therefore you multiply 40 by 4.5 to get 180)

Answer:

Michael ran 180 miles in bad weather.

Answer 2

Answer is 180, 40% of 450 is 180.
