- - If a baker has 20 pounds, and looses 3/4 pounds, then we have to take away. Meaning to subtract.

♥ Start with turning 20 into a fraction.

[tex] \frac{20}{1} - \frac{3}{4} [/tex]

♥ Change this to addition.

[tex] \frac{20}{1} + \frac{-3}{4} [/tex]

♥ Solve for that.

[tex] \frac{80}{4} + \frac{-3}{4} [/tex]

♥ Combine.

[tex] \frac{80+-3}{4} = \frac{77}{4} =19.25[/tex]

She has about 19 (rounded) pounds left.

Decimal exact: 19.25
