4tens --- 40

12 tenths ---- 1.2
and 25 hundredths ----- .25
so 41.25
Weird way to describe a number. 12 tenths??

Do the same with the other, then subtract them

To find the difference between two numbers, we can subtract one number from the other. Let's break down the given numbers:

Number 1: 4 tens 12 tenths and 25 hundredths
In decimal form: 40.12 + 0.25 = 40.37

Number 2: 3 tens 14 tenths and 45 thousandths
In decimal form: 31.45

To find the difference, we subtract the second number from the first number:
40.37 - 31.45 = 8.92

Therefore, the difference between 4 tens 12 tenths and 25 hundredths and 3 tens 14 tenths and 45 thousandths is 8.92.
