Question

Jax collects 43 stamps, and Jane collects 55 stamps. How many stamps do they collect in all?

• A. 43 + 5 + 55 + 5 = 98
• B. 40 + 3 + 55 + 5 = 101
• C. 40 + 3 + 50 + 5 = 98
• D. 43 + 3 + 50 + 5 = 101

Answer 1

The correct option is C 40 + 3 + 50 + 5 = 98

Say:
We know that Jax collects 43 stamps, and Jane collects 55 stamps. Let us find the total.

Steps:

• The options have the numbers in their decomposed form.
• Let us decompose the given numbers.
• 43 = 40 + 3
• 55 = 50 + 5
• Thus, for the total, 43 + 55 = 40 + 3 + 50 + 5 = 40 + 50 + 3 + 5 = 90 + 8 = 98.
• Hence, option B is correct.
