If: x+10 = 25 Then: x = 15
X/10 * 15/25 = 6 x=6
8 is 10% of 80, so X = 10. 25% of 10 is 2.5
10 of 25 = 10/25 = 40% percentage = 10/25 x 100 = 1,000/25 Answer: 40%
2 x 5 = 10 5 x 5 = 25
(4 x 25 + 1) x 10
Discount = (40) x (25/100) = (4) x (25/10) = 100/10 = 10
XXV X=10, V=5 10+10+5=X+X+V=XXV=25
150 10 x 15 = 150 15 x 10 = 150 25 x 6 = 150
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
5 x 25 x 10 x 400 = 500000
