Estimating products

[Guest]

Using rounding or compatible numbers to estimate to the nearest whole number is the answer to these problems correct?

a) 3/4 x 77 = 60

b) 208 x 2/3 = 186

c) 185 x 7/9 = 140

d) 71 x 6/7 = 60


Please let me know if these are correct.

Thank-you!

It seems correct, except b) is a bit off.
