I have answered C because both of the sides of the equation must equal to each other, so if I found out 9 ÷ 15, then I could reverse it and multiply from 10 to A. 9 ÷ 15 = 0.6, so 10 x 0.6 is A. 10 x 0.6 is 6 and that is why I chose C!

I knew 5 times 3 is 15. So if the fraction had a denominator of 5, the numerator will be 3. So if the denominator is 10, then the numerator is 6.

I know it’s c because if I did a/10 x3 = b/30 % 2 = 9 /15 so you do the inverse so my answer is 6

I know that 9 fifteens are equivalent to 3 fifths so if you times 3 fifths by 2 it will equal 6 tenths
