Amanda baked 64 cookies with 8 scoops of flour. With 12 scoops of flour, how many cookies can Amanda bake? Solve using unit rates.

Answer 1

To solve this problem using unit rates, we can set up a proportion.

Since the number of cookies is directly proportional to the amount of flour used, we can write the following ratio:

8 scoops of flour/64 cookies = 12 scoops of flour/x cookies

To find the value of x, we can cross-multiply and solve for x.

8x = 64 * 12
8x = 768

Dividing both sides of the equation by 8, we get:

x = 768/8 = 96

Therefore, Amanda can bake 96 cookies with 12 scoops of flour.

Answer 2

Brett read a total of 15 books over 3 months. If Brett has read 95 books so far, how many months has he been with his book club? Solve using unit rates.

Answer 3

To solve this problem using unit rates, we can set up a proportion.

Since the number of books is directly proportional to the number of months, we can write the following ratio:

15 books/3 months = 95 books/x months

To find the value of x, we can cross-multiply and solve for x.

15x = 3 * 95
15x = 285

Dividing both sides of the equation by 15, we get:

x = 285/15 = 19

Therefore, Brett has been with his book club for 19 months.

Answer 4

Rose baked 90 cookies with 5 scoops of flour. With 6 scoops of flour, how many cookies can Rose bake? Solve using unit rates.

Answer 5

To solve this problem using unit rates, we can set up a proportion.

Since the number of cookies is directly proportional to the amount of flour used, we can write the following ratio:

5 scoops of flour/90 cookies = 6 scoops of flour/x cookies

To find the value of x, we can cross-multiply and solve for x.

5x = 90 * 6
5x = 540

Dividing both sides of the equation by 5, we get:

x = 540/5 = 108

Therefore, Rose can bake 108 cookies with 6 scoops of flour.
