Determine if each pair of ratios are equivalent. 17. 8/5,24/20 18. 0.5/10,5/100 19. 1.3/5.2,12/48

Step-by-step explanation:

There are several ways you can determine the equivalence of two ratios:

For these problems, these methods look like ...

17. In lowest terms: 8/5 and 6/5. (not equivalent)

Performing the division: 1.6 and 1.2. (not equivalent)

Multiplying each by 100: 160 and 120. (not equivalent)

___

18. In lowest terms: 1/20 and 1/20. (equivalent)

Performing the division: 0.05 and 0.05. (equivalent)

Multiplying each by 1000: 50 and 50. (equivalent)

___

19. In lowest terms: 1/4 and 1/4. (equivalent)

Performing the division: 0.25 and 0.25. (equivalent)

Multiplying each by 249.6: 62.4 and 62.4. (equivalent)

1) c 2143.6 cm

2) c 113.0 m

3) a 33.5 ft

4)   d 2 cm

5) c 20 mm

6) 180 in

7) d 120 ft

step-by-step explanation:

the multiplicative inverse of a fraction a/b is b/a. for the multiplicative inverse of a real number, divide 1 by the number. for example, the reciprocal of 5 is one fifth 1/5 or 0.2, and the reciprocal of 0.25 is 1 divided by 0.25, or 4.
