13 x 50 = 150 + 500 = 650 650 - 13 = 637
650 x 650 = 422,500
650 = 2 x 5 x 5 x 13
5 x 650 = 3,250
Expressed as a percentage, 70/650 x 100 = 10.769230 recurring (that is, 10.769230769230...) percent.
13 x 50 = 150 + 500 = 650 650 - 13 = 637
10% of 500 = 50 30% = 50 x 3 =150 Now to increase 500 by 30%: 500 + 150 = 650
650 x 650 = 422,500
2 x 5 x 5 x 13 = 650
650 = 2 x 5 x 5 x 13
Each of these equals 650: 1 x 650, 2 x 325, 5 x 130, 10 x 65, 13 x 50, 25 x 26
x(x+1) = 650 25*26 = 650
