Answer 2

`Pounds\ of\ ground\ meat\ use\ for\ the\ hamburgers\ is\ (173)/(80)\ pounds.`

Explanation:

As given

`Keith\ bought\ a\ package\ with\ 2 (9)/(16)\ pounds\ of\ ground\ meat\ to\ make\ hamburgers.`

i.e

`Keith\ bought\ a\ package\ with\ (41)/(16)\ pounds\ of\ ground\ meat\ to\ make\ hamburgers.`

`He\ has\\frac{2}{5}\  pounds\ of\ ground\ meat\ left.`

Pounds of ground meat use for the hamburgers = Total amount of meat Keith bought for make hamburgers - Amount of meat left

`Pounds\ of\ ground\ meat\ use\ for\ the\ hamburgers = (41)/(16) - (2)/(5)`

L.C.M of (16,5) = 80

`Pounds\ of\ ground\ meat\ use\ for\ the\ hamburgers = (41* 5 - 2* 16)/(80)`

`Pounds\ of\ ground\ meat\ use\ for\ the\ hamburgers = (205 - 32)/(80)`

`Pounds\ of\ ground\ meat\ use\ for\ the\ hamburgers = (173)/(80)`

`Therefore\ pounds\ of\ ground\ meat\ use\ for\ the\ hamburgers\ is\ (173)/(80)\ pounds.`
