Answer 1

\[\huge~\rm~\frac{ 15\times 10=? }{ 8\times 9=?}\]

Answer 2

yeah that's how I would do it. Keep change the sign from division to multiplication and flip the second number. then multiply across the numerator and denominator.

Answer 3

150/72

Answer 4

Good now simplify that

Answer 5

Answer 6

can you find the GCF of 150 and 72?

Answer 7

no

Answer 8

We know they are both even numbers right so 2 is possible
150 divided by 2=?
72 divided by 2 =?

Answer 16

It may be easier to see how to simplify this if you factor the numbers before multiplying them, then cancel terms which appear in both numerator and denominator:

\[\frac{15}{8}\div\frac{9}{10} = \frac{15}{8}*\frac{10}{9} = \frac{15*10}{8*9} = \frac{3*5*2*5}{2*2*2*3*3} \]\[= \frac{\cancel{2*}\cancel{3*}5*5}{\cancel{2*}\cancel{3*}2*2*3}=\frac{5*5}{2*2*3} = \]

I agree that the correct answer to the question as you have provided it here does not appear in your list of answer choices.
