NUMBERS: DECIMAL MULTIPLICATION & DIVISON
Decimal multiplication is a way of multiplying decimal numbers but using fractions as well as decimals to times. Here is an example:
EG1: 3 x 4.2=?
=5 x 12/10
=5x12/10
Then, you just time is like a normal multiplication.
=60/10
60 divided by 10 is 6
so the answer is : ? = 6.

Decimal division is a way of dividing decimal numbers but using fractions as well as decimals to times. Here is an example:
EG2 : 0.20/0.05=?
= 0.20/0.05 x 100/100
We do this to make the number a whole number
=20/5
So as a result the answer would be...
...?=4
