Question

1. evaluate the expression: 1.2 + 0.35

1.5
1.25
1.55
1.45

Explanation:

Step1: Align decimal points

Write \(1.2\) as \(1.20\) to align with \(0.35\) (same number of decimal places).

Step2: Add the numbers

Add the tenths and hundredths places: \(0.20 + 0.35 = 0.55\), and the whole number part is \(1\). So \(1 + 0.55 = 1.55\).

Answer:

1.55 (corresponding to the option "1.55")
