Estimate 16 20/30 x 28 3/7 - 4 13/25

+ 8 2/47 as a whole number or

as a mixed number where the

fractional part is 1/2.

A. 452

B. 480

C. 488

D. 492 1/2

I am trying to work this, and am

coming up with (D) 492 1/2.

Will you please see if I am right

and what you come up with?

Thank you so very much!

Your question should use parentheses to indicate the order of operations.

(a x b) - c is not the same as a x (b-c)

None of your choices are very close, if the multiplication comes first. Let's use decimals to show that.

16 20/30 = 16.667

28 3/7 = 28.429

4 13/25 = 4.520

8 2/47 = 8.043

(16.667 x 28.429) - 4.520 - 8.043 = 461.263

The choices of my answers are

452,480, 488, 492 1/2

Please help!!!
