Question

One student ate 3/20 of all candies and another 1.2 lb. The second student ate 3/5 of the candies and the remaining 0.3 lb. What weight of candies did they each eat?

Answer 1

Answer:

First ate 2.1 lb., second one ate 3.9 lb

Step-by-step explanation:

Let there are x pounds of candies total, then

$\frac{3}{20}$ x + 1.2 + $\frac{3}{5}$ x + 0.3 = x

x - $\frac{3}{4}$ x = 1.5

$\frac{1}{4}$ x = 1.5 ===> x = 6 lb

One student ate: $\frac{3}{20}$ x + 1.2 = 0.9 + 1.2 = 2.1 lb

Another one ate: $\frac{3}{5}$ × 6 + 0.3 = 3.6 + 0.3 = 3.9 lb
