Question

Multiply $0.6845by400$

Answer 1

Step 1. Multiply the given decimal numbers normally, ignoring the decimal points.

$6845\times 400=2738000$

Step 2. Then put the decimal point in the answer; it will have as many decimal places as the two original numbers have altogether. (Count total number of decimals places in both the number and put decimal in answer counting from right)

$0.6845\times 400=273.8000$

Hence, result is $273.8$
