The problem asks to compute two values: First, decrease 90 by 20%. Second, find 60% of 250.

1. Problem Description

The problem asks to compute two values:

First, decrease 90 by 20%.

Second, find 60% of

2

5

0.

2. Solution Steps

First, we need to decrease 90 by 20%. This means we need to calculate 20% of 90 and then subtract that from

9

0.

$20\% \text{ of } 90 = \frac{20}{100} \times 90 = 0.20 \times 90 = 18$

Then, we subtract 18 from 90:

$90 - 18 = 72$

Next, we need to find 60% of

2

5

0.

$60\% \text{ of } 250 = \frac{60}{100} \times 250 = 0.60 \times 250 = 150$

3. Final Answer

Decreasing 90 by 20% gives

7

2. 60% of 250 is 150.
