Question

1. 48.55 + k = 61.77

48.55 + k - \square = 61.77 - \square
k = \square

Explanation:

Step1: Apply Subtraction Property of Equality

To isolate \( k \), we subtract \( 48.55 \) from both sides of the equation \( 48.55 + k = 61.77 \). So we have \( 48.55 + k - 48.55 = 61.77 - 48.55 \).

Step2: Simplify Both Sides

Simplifying the left side: \( 48.55 - 48.55 + k = k \). Simplifying the right side: \( 61.77 - 48.55 = 13.22 \). So \( k = 13.22 \).

Answer:

The first two boxes are \( 48.55 \) and \( 48.55 \) respectively, and the last box is \( 13.22 \).
