Question

Do 1.7 and 1.700 have the same value, explain why or why not

Answer 1

1.7 and 1.700 have the same value, this is because any 0's after the 7 don't change the value. They don't change the value because it is after the decimal point. If it was before the decimal point then the value would change.

Answer 2

Yes, Because zeroes after decimal point on right side of a number are not significant .

Explanation:

We are given that 1.7 and 1.700

We have to tell both decimal have same value and explain why both decimal have same value .

In order to check both decimal have same value we write decimal number in fraction form

1.7 can be written as

1.7=
`(17)/(10)`

1.700 can be written as

`1.700=(1700)/(1000)`

`1.700=(17)/(10)`

Therefore, both decimal number have same value.

Because zeroes after decimal point on right side of a number are not significant .
