Question

How do you write 2.22 in expanded form

Answer 1

2 in expanded form is 2 + 2/10 + 2/100= 2.22

Answer 2

`2 + (2)/(10)+(2)/(100)`

Explanation:

In the expanded form we write a number as the sum of all place value of its digits from left to right,

Here, the given number,

2.22

By the place value chart,

Place value of first digit = 2 ( ones )

Place value of the first digit after decimal =
`(2)/(10)` ( tenth )

Place value of the second digit after decimal =
`(2)/(100)` ( hundredth )

`\implies 2.22 = 2 + (2)/(10)+(2)/(100)`
