Question

What is the solution for x in the proportion ten over sixteen equals five over x?

Answer 1

Cross-multiply, then divide.

Answer 2

ok :D but divide by what

Answer 3

After you cross-multiply, it should be clear. ;)

Answer 4

the answer is 10 then right

Answer 5

OR, just look at the proportion and determine what x will make the ratios equal.

Eg.
10/16 = 5/x
So, what do you "do" to 10 to get 5?

Do that same operation to 16, and you'll have x.

Answer 6

the answer for x is not 10. If you mean, what you divide by (if you cross multiply),t hen yes, that would be 10.
