Question

Jen buys sesame bagels and plain bagels. If the ratio of sesame to plain is 1:3 and Jen bought 2 dozen bagels, what percent of the bagels are plain? How many bagels are plain? Suppose each plain bagel has 0.53 gram of salt, and each sesame bagel has 0.65 grams. Use a percent to compare the amount of salt in a plain bagel to that in a sesame bagel.

Answer 1

if the ratio is 1:3, then 3/4 are plain, no matter how many she bought
3/4 * 24 = ?
the salt ratio is clearly 0.53/0.65
