Answer 1

let the amount of soybean meal be x
then the amount of cornmeal is 240-x

so .12x + .06(240-x) = .08(240)

Im not good at algebra what do i multiply?

Answer 3

.12x + .06(240-x) = .08(240)

Both sides multiplied by 100.

12x + 6(240-x) = 8(240)

Get rid of the parentheses by multiplying again.

I hope this helps a little more.
