A baker uses 1/6 feet of cookie dough to make each cookie. How many feet of cookie dough will he need to make 15 cookies?
(1/6) * 12 = 12/6 = 2 inches
2 * 15 = 30 inches = _______ feet
or, 1/6 * 15 = 5/2 feet
To find out how many feet of cookie dough the baker will need to make 15 cookies, we need to multiply the amount of cookie dough needed for each cookie by the total number of cookies.
The baker uses 1/6 feet of cookie dough for each cookie. So, to find out how much dough is needed for 15 cookies, we can use the following calculation:
1/6 (feet of dough per cookie) * 15 (number of cookies)
To simplify this calculation, we multiply the numerators first:
1 * 15 = 15
Then we multiply the denominators:
6 * 1 = 6
So, the final calculation is:
15/6
To convert this fraction to a mixed number or decimal, we can divide 15 by 6:
15 ÷ 6 = 2 remainder 3
Therefore, the baker will need 2 and 3/6 (or simplified as 2 and 1/2) feet of cookie dough to make 15 cookies.
