Answer:
let's say theres 30 dogs
so 4:1 not simplified is 120:30
the ratio of dogs to cats would be 30:20
(3x10 = 30 and we have to do 2x10 as well which would equal 20)
120:20 would be the Ratio of ppl to cats
simplified
120/20 = 6
20/20 / 1
6:1

Answer:
0.048 kgm/s, 6.88 kgm/s
Explanation:
m = 0.003 kg, M = 0.43 kg, v = 16 m/s
The momentum of a table tennis ball = mv = 0.003 * 16 = 0.048 kgm/s
The momentum of a soccer ball = Mv = 0.43 * 16 = 6.88 kgm/s
The two balls have same speed, but different masses. A table tennis ball has smaller mass, so the momentum is smaller too.
