Answer:

60% = \frac{3}{5}

75% = \frac{3}{4}

84% = \frac{21}{25}

65% = \frac{13}{20}

Step-by-step explanation:

60% = \frac{3}{5} because 3 ÷ 5 = 0.6

75% = \frac{3}{4} because 3 ÷ 4 = 0.75

84% = \frac{21}{25} because 21 ÷ 25 = 0.84

65% = \frac{13}{20} because 13 ÷ 20 = 0.65

The way I figured this one out was saying that if it takes 2lbs to stretch it to 12 inches and 5lbs to stretch to 18 inches that means that 3 additional pounds = 6 inches. Therefore, each additional pound is 2 inches. We know already that with 2 lbs it was 12 inches in length and we can also say that 2 lbs = 4 inches. So subtract 4 from 12 and you end up with the answer of 8 inches.
