25 PERCENT AND 90 PERCENT OF 80
I always found it easier to change it to a fraction first. 25 percent is 1/4. Now you divide the number into the denominator (bottom number in a fraction) 80/4=20 and then multiply by the top number. So the first answer is 20. Try the second one. I'll be happy to check it.
x/80 = 25/100
x/80 = 90/100
set both equal to x to find percentage
To calculate 25 percent of 80, you would multiply 80 by 0.25.
25% = 0.25
So, 25 percent of 80 is 80 x 0.25 = 20.
To calculate 90 percent of 80, you would multiply 80 by 0.90.
90% = 0.90
So, 90 percent of 80 is 80 x 0.90 = 72.
Therefore, 25 percent of 80 is 20, and 90 percent of 80 is 72.
