408 bags of dog food
Step-by-step explanation:
The question asks for the total bags of dog food. Because they give you two existing values expressing how much dog food of each type there is, all you must do is add them together. 145 + 263 = 408
(-79.54) / (-9.7) = <span>8.2
Steps:
</span>
<span><span>Conversion: 79.54 = <span>7954/100</span> = <span>3977/50
</span></span><span>Unary minus: -79.54 = -<span>3977/50</span></span><span>
Conversion: 9.7 = <span>97/10</span></span><span>
Unary minus: -9.7 = -<span>97/10
</span></span><span>Divide: -<span>3977/50</span> / (-<span>9710</span>) = <span>-397750</span> · <span>10-97</span> = <span>-3977 · (-10)50 · 97</span> = <span>397704850</span> = <span>415
</span>To divide one fraction by another, invert (turn upside-down) the second fraction, then multiply.
