Answer 1

Answer:

Step-by-step explanation:

The ratio of donuts to bagels at the bakery is 5 to 2. If there are 25 donuts how many bagels are there?

5/2 = 25 / x  

x = (25/5)(2) = 10 bagels

Knowing that the bakery has 140 items total use the ratio of five donuts to two bagels to determine how many other (of their ?) items are donuts (d) and how many are bagels (b).

d + b = 140

d/b = 5/2

d = 5b/2

5b/2 + b = 140

      7b/2 = 140

            b = 40 bagels

    d + 40 = 140

            d = 100 donuts
