Find the new amount.

#6)
Decrease 8 by 75%.

#7)
Decrease 135 by 22%.

I don't know how to solve and show work

8 * 0.75 = ?

thnx

dont you need to subtract too?????????????

To find the new amount after a percentage decrease, you need to multiply the original amount by the decrease percentage (expressed as a decimal) and then subtract that result from the original amount.

For the first problem (#6), we need to decrease 8 by 75%. To do this, we first convert 75% to a decimal by dividing it by 100: 75/100 = 0.75. Then, we multiply the original amount (8) by the decimal (0.75): 8 * 0.75 = 6. Finally, we subtract the result (6) from the original amount (8): 8 - 6 = 2.

Therefore, the new amount after a 75% decrease is 2.

For the second problem (#7), we need to decrease 135 by 22%. Following the same process, we convert 22% to a decimal: 22/100 = 0.22. Then, we multiply the original amount (135) by the decimal (0.22): 135 * 0.22 = 29.7. Finally, we subtract the result (29.7) from the original amount (135): 135 - 29.7 = 105.3.

Therefore, the new amount after a 22% decrease is 105.3.
