10 acres = 750 bushels of corn

14 acres = x

Cross multiply.
10/750 and 14/x
=10500/10x

Divide 10 from the numerator and denominator.
10500/10x divided by 10/10
=1050/x

To remove x, multiply.
x(1050/x)
=1050

So, 14 acres = 1,050 bushels of corn.

Is this correct?

yes

but I just said 1.4*750:)
