Question

a baker has 20 pounds of sugar. He uses 3/4 of the sugar to bake muffins. How many sugar does he have left?

Answer 1

- - 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.


`(20)/(1) - (3)/(4)`

♥ Change this to addition.


`(20)/(1) + (-3)/(4)`

♥ Solve for that.


`(80)/(4) + (-3)/(4)`

♥ Combine.


`(80+-3)/(4) = (77)/(4) =19.25`

She has about 19 (rounded) pounds left.

Decimal exact: 19.25
