Question

In the last two years, Mari grew 2 1/4 inches, Kim grew 2.4 inches, and Kate grew 2 1/8 inches. Write the amounts they grew in order from least to greatest

Answer 1

First, let's turn the fractions into decimal form so you can see the answer, more clearly.
2
`(1)/(4)` = 2.25
2.4 = 2.4
2
`(1)/(8)` = 2.125

Now, after looking at the decimals, we can see which decimals are the biggest. They would order, from least to greatest, like this.
1) 2.4
2) 2.25
3) 2.125

I hope this helps!

Answer 2

`\text{Growth in Kate}<\text{Growth in Mari}<\text{Growth in Kim}`

Explanation:

We are given the following information in the question:

Growth in Mari =

`2\displaystyle(1)/(4)\text{ inches} = (2* 4 + 1)/(4) = (9)/(4) = 2.25\text{ inches}`

Growth in Kim =

2.4 inches

Growth in Kate =

`2\displaystyle(1)/(8)\text{ inches}= (2* 8 + 1)/(8) = (17)/(8) = 2.125\text{ inches}`

Growth in order from least to greatest:

`2.125<2.25<2.4\\\text{Growth in Kate}<\text{Growth in Mari}<\text{Growth in Kim}`
