Question

When multiplying decimals_______the product first

Answer 1

1. When multiplying desimals, estimate the product first.

2. This will help you place the decimal point in the product.

3. Last check to see if your answer is correct.

`(3.78)\cdot(4.1)`

estimate the product without the decimals

`(378)\cdot(41)=15498`

count the number of decimal places there are on both numbers

`\begin{gathered} 3.78\Rightarrow2 \\ 4.1\Rightarrow1 \end{gathered}`

there are 3 decimal places in the product, move the decimal place from right to left as many decimal places you found.

`(3.78)\cdot(4.1)=15.498`
