SESK: Stuff Everyone Should Know · sesk.info/asvab-ar-ratio-parts
A ratio is 3:5. If the total is 64, what are the parts?
24 and 40, because 3 + 5 = 8 equal parts.
- 20 and 44
- 18 and 46
- 24 and 40 ✔
Why: 3 + 5 = 8 equal parts. Each part is 64 ÷ 8 = 8. Multiply: 3 x 8 = 24 and 5 x 8 = 40.
Huh, didn't know that: Ratios compare parts; the whole is the sum of the parts.
What did the ratio say to the fraction? You complete me.
