Question

Which two ratios represent quantities that are proportional?​

Answer 1

Answer:

• D. 45/18 = 35/14

Step-by-step explanation:

Lets simplify the ratios where possible and compare:

• A. 3/4 = 9/12 ≠ 5/12
• B. 32/20 = 16/10 ≠ 22/10
• C. 7/5 = 14/10 ≠ 14/9
• D. 45/18  = 5/2 (divide by 9) and 35/14 = 5/2 (divide by 7)

The last two ratios represent proportional quantities
