Question

Which phrase implies the expression, y divided by sixteen?

Answer 1

I don't really understand your question but do you mean like this:
the quotient of y and 16?

Answer 2

given that you have y divided by sixteen, then a) sixteen divided by y is obviously NOT the one b) "sum" means to add, not divide so you're left to ponder either c) quotient of sixteen and y d) the quotient of y and sixteen

Answer 3

It's D :)
