A farmer has 240 acres under cultivation at the cost of $188.99 per acre. If he averages a yield of 60 bushels per acre, what profit is expected if the price per bushel is $5.67?

The proportion equation of the ratio 100:2=60:X is

\(\frac{100}{2}=\frac{60}{X}\)

Cross-multiply to find the value of X

\(100x\ =\ 120\)

Divide both sides by 100

\(\frac{100x}{100}=\frac{120}{100}\)

\(x\ =\ 1.2\)

The value of X is 1.2

First step is to find the least common divisor of the denominators 19, 25, 5 and 15, which is 1425

Next, multiply each fraction with 1425 as follows

\(\frac{4}{19}\)* 1425=300

\(\frac{4}{25}\)* 1425=228

\(\frac{3}{5}\)* 1425=855

\(\frac{3}{15}\)* 1425=285

From the calculations above, 855 is the largest number among the four computed numbers. Then, it follows that\(\frac{3}{5}\) is the largest number.

Divide the numerator by 5 as follows

\(\frac{9.6}{0.8}=12\)
