The ratio of John’s collection of baseball cards to Billy’s collection is 8 to 5 if John has 100 cards how many does Billye have round your answer to the nearest whole number?

Answer 1

If the ratio of John's collection to Billy's collection is 8 to 5, we can set up a proportion: 8/5 = 100/x.

Cross-multiplying, we get 8x = 500.

Dividing both sides by 8, we find that x = 62.5.

Round to the nearest whole number, we find that Billy has approximately 63 cards.
