What is 1/4 of 40?
10
Estimate this problem and choose one answer:
169 ÷ 13
A. 5 B.10. C. 12 D. 15
Since 13 x 10 = 130 it will be a little over, so 12 is the closest answer.
Since 5 x 13 is a half fact, we know that it will be 65 which puts it far above 169.
If 1 pound of fudge costs $4.25, what is the cost of 10 pounds?

What is 3/4 of 36?
27
Estimate this problem and choose one answer:
624 ÷ 26
A. 25 B.26 C. 27 D. 30
Since we can do 10 x 26=260 we know it doubled and its half fact.
5 x 26= 130
20 x 26 = 520
520+130= 650 which means the answer is close to 25.
