Question

ting with 48, show one way to make an expression with a sum of 75.
48
48
20 10 5 2 +

Explanation:

Step1: Find the number to add to 48

We know that \( \text{Sum} = 48 + x = 75 \), so \( x = 75 - 48 = 27 \). Now we need to make 27 using the given numbers (20, 10, 5, 2) and addition.

Step2: Combine numbers to get 27

We can use \( 20 + 5 + 2 = 27 \). Then the expression is \( 48 + 20 + 5 + 2 \).

Step3: Verify the sum

Calculate \( 48 + 20 + 5 + 2 = 48 + 27 = 75 \), which matches the required sum.

Answer:

\( 48 + 20 + 5 + 2 \) (or other valid combinations like \( 48 + 10 + 10 + 5 + 2 \), but the first one is simpler with the given numbers)
