I want to run 4 1/2 miles tonight. If I know running around my block is 3/5 of a mile, how many times should I run around the block to get my 4 1/2 miles of running in

3/5 block mile is also 0.6 block mile
4 1/2 miles is also 4.5 miles

How many 0.6mi blocks do you run to run 4.5 miles?

4.5miles/0.6block mi = 7.5 or 7 1/2 blocks will equal 4.5 or 4 1/2 miles.

Check 7.5 blocks x 0.6 block mi = 4.5 miles

Same as you know one quarter equals $0.25 cent. And how many do you need to make one dollar that equals $1.00 ?

1/ .25 = 4 quarters

than do 23.50 times 18 and then divide your answer by 100 than you will get x.
