Question

Which partial products can be added to equal 89 × 3?
Choose exactly two answers that are correct.
a. 8 × 3
b. 9 × 3
c. 80 × 3
d. 90 × 3

Answer 1

I would say answers B and C.  If you multiply 80x3 and 9x3, then add those products together, you'll get the same answer as 89x3

Answer 2

B and C 

Its pretty simple, especially for highschool...
