Which correctly explains how to estimate 33 percent of 87?
a)round 33 percent to 20 percent and 87 to 80. think of 20 percent as 10 percent + 10 percent. find 10 percent of 80 as 8. so, 30 percent of 80 is 8 + 8, which is 16.
b)round 33 percent to 30 percent and 87 to 90. think of 30 percent as 10 percent + 10 percent + 10 percent. find 10 percent of 90 as 9. so, 30 percent of 90 is 9 + 9 + 9, which is 27.
c)round 33 percent to 35 percent and 87 to 90. think of 35 percent as 10 percent + 10 percent + 10 percent. find 10 percent of 90 as 9. so, 35 percent of 90 is 9 + 9 + 9, which is 27.
d)round 33 percent to 40 percent and 87 to 80. think of 40 percent as 10 percent + 10 percent + 10 percent. find 10 percent of 80 as 8. so, 40 percent of 90 is 8 + 8 + 8, which is 24.
