Simplest form of:
12/30=2/5
12/20=3/5
21/35=3/5
It doesn't
remember that
(x/g) times (y/z)=(x time y)/(g times z) so
2pi/4=(2 times pi)/(4 times 1) so
2pi/4=2/4 times pi/1=1/2 times pi/1=pi/2
The answer would be the Last option (D). This because it poses the proportion of 48 in (Amber's height) / 60 in (Lucy's height) and puts it equal to the proportion of x (what is Amber's height in the photo) / 3 (what is Lucy's height in the photo. Hope this helps :)
(5^10 * 7^14)^10 =
5^(10 * 10) * 7^(14 * 10) =
5^100 * 7^140....its C....because ur multiplying the exponents
