What is 123.54 minus 25.4?

Explanation:
Subtracting decimals means lining up the decimal points and subtracting place by place from right to left. First make the places match by writing 25.4 as 25.40. Then subtract 123.54 minus 25.40. Hundredths: 4 − 0 = 4 Tenths: 5 − 4 = 1 Ones: 3 − 5 requires borrowing from the tens. Borrow 1 from the 2 (tens), turning 3 into 13 and the 2 into 1. Then 13 − 5 = 8 Tens: now 1 − 2 requires borrowing from the hundreds. Borrow 1 from the 1 (hundreds), turning the 1 into 0 and the tens into 11. Then 11 − 2 = 9 Hundreds: 0 − 0 = 0 So the result is 98.14.

Hundredths: 4 − 0 = 4

Tenths: 5 − 4 = 1

Ones: 3 − 5 requires borrowing from the tens. Borrow 1 from the 2 (tens), turning 3 into 13 and the 2 into 1. Then 13 − 5 = 8

Tens: now 1 − 2 requires borrowing from the hundreds. Borrow 1 from the 1 (hundreds), turning the 1 into 0 and the tens into 11. Then 11 − 2 = 9

Hundreds: 0 − 0 = 0

So the result is 98.14.
