Multiplying a number by which of the following would result in a smaller number?
a.10 0
b.10 1
c.10 2
d.10 -1

D because if you multiply by a negative it will result in a smaller number unless you multiply a negative times a negative which will result in a positive.

I believe it would be D since you multiply by a negative which would give you -10.

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.
