Simplify these ratios.

7 1/4 inches to 2 feet.

$0.02 per $1.75


Hi Mike,

In you mulyiply both numbers in ratio by the same non-zero number, the ratio remains unchanged. This is exactly the same process as multiplying the numerator and denominator of a fraction by the same non-zero number. Hence for your second problem,

0.02 per 1.75 I would multiply both numbers by 100 to remove the fractionl part. Thus the equivalent ratio is

2 to 175

In the first problem express both numbers in the same units (probably inches) and express the number on the left as a fraction. Can you now finish the problem so tht both numbers in the ratio are integers?
