5.8 multiplied by 8.7?
When you are multiplying two numbers with decimals, it's easy to do.First, multiply the numbers as if there were not decimals there:~5.8x8.7____~406464_____5046... then, count the number of places for the decimal points, and add them together. 5.8 = 1 decimal place, 8.7 = 1 decimal place, the two added together are 2 decimal places. So your answer, 5046 needs to have two decimal places; or 50.46(I'm sorry, I had to use a ~ to keep spacing correct... I'm having problems pushing a nbsp into the code... lol)
