Question

Wich of the following is the correct value of 0.22 0.4?

Answer 1

The decimal place will be placed to the left by the total number of digits after the two numbers.

Explanation:

The multiplication we are asked to perform is

`1.35*4.2`

which has a total of 3 digits after the decimal point.

Now we know that

`135*42=5670`

therefore, to find 1.35 x 4.2 we just shift the decimal place in the above to the left by 3 units

therefore

`1.35*4.2=5.67`

which is our answer!
