Answer:

8/8

Explanation:

16/40 as a fraction is 0.4, and it's the same for 2/5. When you're diving fractions you can se KCF, where you keep the first fraction, change the sign (in this case a division symbol) to multiplication, and then flip the fraction (if it was 2/3 then it would now be 3/2).

Regardless, when dividing 2 of the same numbers you'll always get one (disregarding 0) to my knowledge atleast, and 8/8 is the same as 1, 2/2, 3/3, 4/4, and so on, therefore, any of these can be your answer if it equates to one.

Explanation:

16/40 / ?/? = 2/5

16/40 = 2/5 × ?/?

?/? = 16/40 / 2/5

a division between 2 fractions can be fine in 2 ways (it is technical the same way, but it looks a little bit different) :

a/b / c/d = a×d / b×c

a/b / c/d = a/b × d/c = a×d / b×c

16/40 × 5/2 = 16×5 / 40×2 = 16 / 8×2 = 8/8

?/? = 8/8
