Hi there!
To find your answer, let us see what number can go evenly into 17 and 147.

Since it looks like nothing can go into each number evenly,
is already simplified down to its lowest terms and it can't go any lower than that.
Hope this helps! :D

1/2 of 14 is 7. multiply 14/1 to 1/2.
3/5 = .60, 65% = .65, 0.70 is the greatest
200 miles. 2.5 divided by 3/4 is 3.33333-, multiplying the given by 60 would give us 199.98, which you can round to 200.
