Question

How did you compute products of dollar amounts that were not whole numbers for example how did you compute the cost of 4 pounds of beef at $5.89 per pound uses example to explain your strategy

Answer 1

$ 23.56

Step-by-step explanation

Step 1

to find the total , we need to multiply the number of pounds by the rate,

so

a)

Multiply as you would with whole numbers( ignore the decimal dot)

so

`589\cdot4=2356`

b)Count the total number of decimal places in your factors.

`\begin{gathered} 4\Rightarrow0\text{ decimals} \\ 5.89\Rightarrow2\text{ decimals} \\ so\text{ total decimals = 2} \end{gathered}`

c)Move the decimal point in the product one place to the left for each decimal place you counted.

`\begin{gathered} 2356\Rightarrow2\text{ places }\Rightarrow23.56 \\ \end{gathered}`

therefore, the result would be

$ 23.56

I hope this helps you
