25/100 = 10/x Cross-multiply the 25 and x and then the 100 and the 10 so 25x=1000 Divide both sides by 25 and you get 40 25x/25 = 1000/25 x = 40 So 25 percent of 40 is 10

25% of 10 = 10*25/100 = 2.5
to calculate the percent increase . first = 25 - 10 = difference between the two numbers = 15 then divide this differnece by the original starting number (which is 10)= 15 divided by 10 = 1.5 to make this a percent increase multiply by 100 . so you result is 1.5 x 100 = 150% to summarise: ((final number- starting number) / starting number) x 100 = percent increase
100% = 700 10% = 70 2.5% = 10%/4 = 70/4 = 17.5
