decrease 5m by 20%
To decrease 5m by 20%, you need to calculate 20% of 5m and subtract it from the original value.
20% of 5m is (20/100) * 5m = 1m.
So, to decrease 5m by 20%, you subtract 1m from 5m.
5m - 1m = 4m.
Therefore, the result is 4m.
To decrease 5m by 20%, you can follow these steps:
Step 1: Convert 20% to decimal form by dividing it by 100:
20% ÷ 100 = 0.20
Step 2: Multiply 5m by 0.20:
5m × 0.20 = 1m
Step 3: Subtract the obtained value from 5m:
5m - 1m = 4m
Therefore, decreasing 5m by 20% gives you 4m.
