Question

Which is not a factor pair of 200? A. 4 and 50 B. 10 and 20 C. 8 and 25 D. 12 and 24

Answer 1

Your answer is D. 12*24=288 not 200.

Answer 2

A factor pair are 2 numbers that multiply to get a certain product.
For 200, we can make factors out of it.
1 x 200, 2 x 100, 4 x 50, 5 x 40, 8 x 25, 10 x 20.
Looking at our answers, the ones that match our factors are:
A.)
B.)
C.)
However, we are looking for the pair that IS NOT a factor.
But D.) does not match, so D is our answer.
I hope this helps!
