Question

Ur planets — a, b, c and d — are orbiting a star. a weighs 0.2 times as much as b does while c weighs 1.2 times as much as d does and four times as much as b does. find the ratio of the weight of a to d, both as a fraction and as a decimal.

Answer 1

Step-by-step explanation:

a:b =0.2:1 =1:5 = 3:15

c:d = 1.2:1 =6:5 = 60:50

c:b = 4:1 =60:15

a:b:c:d = 3:15:60:50

a:d =3:50

a/d = 3/50

=6/100 = 0.06

hope this helps
