Question

Can someone help me with these three questions?

Answer 1

Answer:

1. =

2. <

3. <

Step-by-step explanation:

Note: When comparing decimals you always place both decimals right above each other.

1 is equal to because once you put a 0 behind the 2.1 they are both the same.

2.10

2.1    <add 0 as space holder

2 is less than because they are both negative you are looking for which one is closest to zero.

-4.5   <add 0 as place holder

-4.25   <closest to zero

3 is less than because $\pi$(pie) equals 3.141592654 which is less than 3.2.

3.141   <do not need to add whole decimal

3.2   <add two 0's as a placeholder
