subtract. \n8.11 - 5.5

Explanation:

Step1: Align decimal points

Write ( 8.11 - 5.5 ) as ( 8.11 - 5.50 ) to have the same number of decimal places.

Step2: Subtract column by column

• Subtract the hundredths place: ( 1 - 0 = 1 )
• Subtract the tenths place: ( 1 - 5 ) (can't do, borrow from the ones place). The 8 becomes 7, and the 1 in tenths place becomes 11. So ( 11 - 5 = 6 )
• Subtract the ones place: ( 7 - 5 = 2 )

Putting it together, we get ( 2.61 ).

Answer:

( 2.61 )
