Question

Find the product: (30 gallons 3 quarts 1 pint) x 5A. 153 gallons 15 quarts 1 pintB. 154 gallons 1 quart 1 pintC. 154 gallons 1 pintD. 154 gallons 1 quart

Answer 1

To find : (30 gallons 3 quarts 1 pint) x 5

we get,

`\begin{gathered} 30\text{ gallons}*5=150\text{ gallons} \\ 3\text{ quarts}*5=15\text{ quarts} \\ 1\text{ pints}*5=5\text{ pints} \end{gathered}`

we know that,

1 gallons=4 quarts

1 quarts=2 pints

Using this conversion we get,

`15\text{ quarts}=(15)/(4)\text{gallons}=3\text{ gallons 3 quarts}`
`5\text{ pints}=(5)/(2)\text{ quarts}=2\text{ quarts }1\text{ pint}`

we get,

`(30\text{ gallons 3 quarts 1 pints})*5=150\text{ gallons+15 quarts+5 pints}`

Substitute the conversions we get,

`=150\text{ gallons}+3\text{ gallons+3 quarts+2 quarts + 1 pint}`
`=153\text{ gallons+4 quarts+1quart+1pint}`
`=153\text{ gallons+1 gallon+1 quart+1 pint}`
