To subtract 2 and 6-tenths from 7 and 4-tenths, we subtract the whole numbers separately and then subtract the tenths separately.
Subtracting the whole numbers:
7 - 2 = 5
Subtracting the tenths:
4 - 6 = -2
Now we combine the whole number and the tenths:
5 and -2-tenths
However, since we cannot have a negative value for the tenths, we need to borrow 1 from the whole number to make the tenths positive.
So, we borrow 1 from the whole number 5, which becomes 4, and add it to the tenths -2.
4 - 1 = 3
-2 + 10 = 8
The final answer is 4 and 8-tenths.
