What is the value of \(18.25+6.4-3.075\)?
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → 21.575
Decimals are added and subtracted with the decimal points one below the other; writing every number with the same number of decimal places keeps the columns in line.
\(18.250+6.400=24.650\)
\(24.650-3.075=21.575\)
