To find the number of times Tina has fed the birds, we need to divide the total amount of bird feed she has given by the amount she gives each time.
1 5/6 cups of bird feed is the same as 11/6 cups.
So, the number of times Tina has fed the birds is 27 1/2 / 11/6
To divide fractions, we need to multiply by the reciprocal of the divisor.
27 1/2 / 11/6 = 27 1/2 * 6/11
To multiply mixed numbers, we multiply the whole numbers together, then multiply the fractions separately, and add the two results.
27 * 6 = 162
1/2 * 6/11 = 6/22 = 3/11
Adding the two results together, we get 162 + 3/11
To add mixed numbers, we need to convert them to improper fractions.
162 = 162/1
162/1 + 3/11 = ((162 * 11) + 3) / 11 = 1785/11
The final result is 1785/11, which is a mixed number of 162 3/11.
Therefore, Tina has given food to the birds 162 3/11 times.
This is approximately equal to 162.27 times.
Therefore, the closest option is 162.27, or 25 2/3 times.
tina feeds her birds exactly 1 5/6 small measuring cups of bird feed each time she feeds them. if she has fed them exactly 27 1/2 cups so far, how many times has she given food to the birds?
15 times
29 1/3 times
25 2/3 times
50 5/12 times
