What Is the value of the number 2.25? How can this number be written as a fraction or mixed number

Hello!

This number is written in a decimal form, which is based on the number `10.` The leftmost digit `2` means just `2.` The next digit, `2` also, has `10` times less "weight" and means `2/10.` The next number, `5,` is at the one hundredth's place and means `5/100.`

The number is the sum of these values, i.e.

`2.25=2+2/10+5/100.`

To add `2/10` and `5/100,` express `2/10` as `20/100` (multiply both numerator and denominator by...

Hello!

This number is written in a decimal form, which is based on the number `10.` The leftmost digit `2` means just `2.` The next digit, `2` also, has `10` times less "weight" and means `2/10.` The next number, `5,` is at the one hundredth's place and means `5/100.`

The number is the sum of these values, i.e.

`2.25=2+2/10+5/100.`

To add `2/10` and `5/100,` express `2/10` as `20/100` (multiply both numerator and denominator by `10`).

So `2/10+5/100=20/100+5/100=25/100.` This fraction may be reduced by `25` and is equal to `1/4.` And we got that the number `2.25` is the same as `2` and `1/4.`

It may also be written as an (improper) fraction. Because `2 =8/4,` `2+1/4=9/4.`
