Question

starting with 48, show one way to make an expression with a sum of 75
48 + 20 + 5 + 2
now, use the expression above to complete the equation.
48 + ? = 75

Explanation:

Step1: Calculate the sum of the known addends

First, we find the sum of \(20 + 5 + 2\). \(20+5 = 25\), and \(25 + 2=27\).

Step2: Verify with the total sum

We know that \(48 + \text{?}=75\), so we can also calculate the missing number by \(75 - 48\). But from the expression \(48+20 + 5+2\), we already found that \(20 + 5+2 = 27\), and \(48+27 = 75\). So the missing number is the sum of \(20 + 5+2\), which is \(27\).

Answer:

\(27\)
