2 1/4 is greater than 2.1.

Explanation:

2 1/4 = 2+1/4
1/4 = 0.25
2 + 0.25 = 2.25
2.25>2.1

2.1color(white)("d") < color(white)("d")2 1/4

Explanation:

As both numbers 'contain' 2 you can for now forget about the 2's and just concentrate on number parts that are less than 1.

So we are comparing 1/4 and 0.1

The first decimal place is counting in 10^("ths") so we are comparing:

1/4 and 1/10

The larger the bottom number the 'smaller' is the things that we are counting (top numbers)

As 10 is greater than 4 and the top numbers are the same then 1/10 is 'smaller' than 1/4

Thus 1/10 <1/4

So it follows that

color(white)("dd")ubrace(2 1/10)color(white)("d") < color(white)("d")2 1/4
color(white)("d...")darr
"Same value"
color(white)("d,,,,")uarr
color(white)("d,,") obrace(color(white)(.)2.1color(white)(.))color(white)("d") < color(white)("d")2 1/4
