Answer:

15g

Step-by-step explanation:

Method A: Calculate the percent first

If you decrease an amount by 25%, you end up with 75% of the amount.

75% of 20g = 0.75 × 20g = 15g

Method B: Calculate the decrease first

We start with 20g. To decrease 20g by 25%, we calculate 25% of 20g.

25% of 20g = 0.25 × 20g = 5g

The decrease amount is 5g.

Now we subtract 5g from 20g.

20g - 5g = 15g
