Answer:
45

Solution: you can use the above method or you can cross multiply. That’s mean multiplying the numerator of the left side by the denomination of the right. And the denominator on the left by the numerator on the right (it makes an x shape). Therefore, your algebraic equation should look like this and solve for x

14x=15*42
14x=630
X=630/14
X=45
