Answer 5

The first one is not D.

2/5 = 4/10 = 6/15
As you can see, the fractions need to be equal. Simplify the larger fraction to find the smaller fraction. You can also cross multiply.

Answer 6

to get a cross-product in a proportion you multiply the numerator of one fraction by the denominator of the second
your choice of 8/24 = 15/5 produces
5x8 = 24x15, which is false

choice A) 5/8 = 15/24 ---> 5x24 = 8x15 as requested

for #1, or any of them
to test if a proportion is true, write it down and take the crossproducts, if they are equal then the ratios are equal

4/5, 20/25 ---> 100, 100, so yes that's the one
you picked D
2/5 , 6/16 ---> 32, 30 , NO!
