You can solve this by cross-multiplying.

7/38 = X/147
7 * 147 = 38 * X
1029 = 38 * X
X = 27.08

7/38 = X/147

In a simple proportion, you can cross-multiply - numerator on left * denominator on right = numerator on right * denominator on left

This is the same as clearing the denominators by multiplying both sides by the LCD of the fractions

7(147) = X(38)
1029 = 38X
27.08 = X
