Question

The fruit fly decided to go on a all-vegetable diet. As a result, she now only weighs 90% of what she used to. If the fruit fly currently weighs 0.018 grams, how many grams did she weigh before she went on the diet?

Answer 1

9514 1404 393

Answer:

0.02 g

Explanation:

Let w represent the original weight. The problem statement tells us ...

0.90w = 0.018 g

Dividing by the coefficient of w, we find ...

w = 0.02 g

She weighed 0.02 grams before the diet.
