5 - 2X = 15 subtract 5 from each side - 5 + 5 - 2X = 15 - 5 -2X = 10 divide each side by - 2 X = - 5 check 5 - 2(-5) = 15 5 + 10 = 15 15 = 15 checks
5:15 or 5/15
3x5 5+5+5
3 times 5 = 15 1 times 15 = 15 60/4 = 15 5+5+5 = 15 10+5 = 15 12+3 = 15 The square root of 225 = 15
15 = 100%15 / 100 = 0.15 (1%)5 / 0.15 = 33.333...% (Which is equal to 1/3 or one third)
15. 5 - -10 = 5 + 10 = 15 → 15 + -10 = 15 - 10 = 5
15 = 5 times 3 15 = 5 + 5 + 5 15 = 7 + 7 + 1 15 = 45 - 30
