Respuesta :

if you have no calculator, pretend like the decimals aren’t there then add them back depending on how many places you have after the decimal. for example: 2.5 times 2.5, if you pretend there are no decimals, you get 625, then you have to add the decimals back. since you have 1 digit after each decimal in each number, you add 1+1=2 to get the number of places you have to add back. so you get 6.25

Answer:

You can use multiplication normally. But then you must add the decimals

Step-by-step explanation:

Lets do 24.56 x 32.78

It would equal 8050768 without decimal points

But now we must add the decimal points in, count the amount of numbers that appear after the decimal, which is 4

So 8050768 = 805.0768
