Question

Find the product of each number and 1/100

122.1
11.8
1350.1
1.704

Answer 1

Product of 122.1 and
`(1)/(100)` = 1.221

Product of 11.8 and
`(1)/(100)` = 0.118

Product of 1350.1 and
`(1)/(100)` = 13.501

Product of 1.704 and
`(1)/(100)` = 0.01704

Solution:

The shortcut for dividing decimal numbers by numbers such as 10, 100, and 1000:

Move the decimal point to the left as many places as there are zeros in the factors 10, 100 and 1000.

Product of 122.1 and
`(1)/(100)`:

`$122.1*(1)/(100) =(122.1)/(100)`

= 1.221 (There are 2 zeroes, so move 2 places left)

Product of 122.1 and
`(1)/(100)` = 1.221

Product of 11.8 and
`(1)/(100)`:

`$11.8*(1)/(100) =(11.8)/(100)`

= 0.118 (There are 2 zeroes, so move 2 places left)

Product of 11.8 and
`(1)/(100)` = 0.118

Product of 1350.1 and
`(1)/(100)`:

`$1350.1*(1)/(100) =(1350.1)/(100)`

= 13.501 (There are 2 zeroes, so move 2 places left)

Product of 1350.1 and
`(1)/(100)` = 13.501

Product of 1.704 and
`(1)/(100)`:

`$1.704*(1)/(100) =(1.704)/(100)`

= 0.01704 (There are 2 zeroes, so move 2 places left)

Product of 1.704 and
`(1)/(100)` = 0.01704
