Four 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.

1.	Four 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» Fractional form = 3/50 Decimal form = 0.06 Step-by-step explanation: Given A = 0.2 TIMES B = 0.2B C = 4 times B = 4B C = 1.2 times D = 1.2D therefore D = C/1.2 LET B = X so A = 0.2x RATIO of A to D A:D = 0.2x : C/1.2 A/D = 0.2x * 1.2 / 4x A/D = 2.4 x / 4 x A/D = 0.6/10 A/D = 0.3/5 A/D = 3/50 Fraction form = 3/50 Decimal form = 0.06
