Sagot :
You multiply it the same way you multiply normal numbers. However, there's a twist. Basically, you count how big the decimal place in the decimal number is. Then you put the decimal place in your answer. For example:
2.3
x2.3
= 69
+46
=529 w/ 2 decimal places
=5.29
2.3
x2.3
= 69
+46
=529 w/ 2 decimal places
=5.29
just only multiply like a whole number. then count the number at the right side of decimal point.....
