Therefore, the equivalent expression for is , which matches choice 4.
If we have 67 blocks in total, how many blocks will remain if we remove 5 tens and 4 ones?
Breaking numbers apart helps you understand different ways to represent the same value. In this problem, 7 can be written as 4 + 3, so 36 + 7 becomes 36 + 4 + 3 - same answer, different form!
Look at the answer choices! They show you exactly how to decompose the number. For , the correct choice breaks 7 into 4 + 3.
No! Only the correct decomposition maintains the original sum. Choice 1 gives 33 + 5 + 3 = 41, while the correct answer 36 + 4 + 3 = 43, matching .
This builds number sense and helps you see that the same value can be expressed multiple ways. It's like saying 'a dozen' or '12' - different words, same amount!
Yes! You could break 36 into smaller parts too, but in this problem, the answer choices specifically show decompositions of the second number (7). Always follow what the question asks for.
