let say number = X
2/3 of the number will be = (2/3)×X
= 2X/3
3/4 of the number would be = (3/4)×X
= 3X/4
2/3 of a number when multiplied by 3/4 of the same number makes 338
(2X/3) × (3X/4) = 338
X^2/2 = 338
X^2 = 338 × 2
X^2 = 169 × 2 × 2
X^2 = 13 × 13 × 2 × 2
X^2 = 13^2 × 2^2
X^2 = (13 ×2)^2
X^2 = 26^2
X = 26
X can be -26 as well
answer = +/- 26
