Question

What is the product of 50 × 0.8

Answer 1

Step-by-step explanation

`50\cdot0.8`

To multiply decimals, first multiply as if there is no decimal. Next, count the number of digits after the decimal in each factor. Finally, put the same number of digits behind the decimal in the product

then

Step 1

`\begin{gathered} 50\cdot0.8=500\cdot8\rightarrow1\text{ decimal position} \\ \\ \end{gathered}`

Step 2

`500\cdot8=400`

put the same number of digits behind the decimal in the product (1 )

`400\rightarrow40.0`

Hence
