Question

Use the product of 123 x 47 to find the product of 123 x 0.47. Explain the difference in the two products.

Answer 1

123 x 47 equals 5781. 123 x .47 equals 57.81. The difference is the decimal is moved to the tenth place in the second equation

Answer 2

`123* 0.47=57.81`

Explanation:

We are given that 123 and 47.

We have to find the product of 123 and 0.47 with the help of the product of 123 and 47

Product of 123 and 47=
`123* 47=5781`

Product of 123 and 0.47=
`123* 0.47`

In 0.47 , two digits after decimal then we substitute 100 in the denominator

Then, the product can be written as

`123* (47)/(100)`

We know that product of 123 and 47=5781

Then, substitute the value

`(5781)/(100)=57.81`

Because 100 in the denominator then we substitute decimal after two digits from right side.

Hence, product of 123 and 0.47 =57.81

In 5781, 5 at thousand place, 7 at hundred place, 8 at tens place and 1 at unit place.

But in 57.81 , 5 at tens place , 7 at one's place , 8 at tenth place and 1 at hundredth place.
