If we have 46 blocks in total and we remove 2 tens, how many blocks will remain?
To solve this problem, we'll proceed through the following steps:
Now, let's work through each step:
Step 1: "2 tens" equates to blocks.
Step 2: We are removing 20 blocks from the total of 46 blocks. Using subtraction, we have:
Therefore, after removing 2 tens (which is 20 blocks), the number of blocks that remain is .
If we have 67 blocks in total, how many blocks will remain if we remove 5 tens and 4 ones?
Because "2 tens" doesn't mean 2 blocks - it means 2 groups of 10 blocks each! You need to multiply: blocks to remove.
Think of it like money: 2 ten-dollar bills equals 2. Similarly, 2 tens in blocks equals 20 blocks, not 2 blocks.
Yes! Write 46 as 4 tens + 6 ones. Remove 2 tens: tens remain. So you have 2 tens + 6 ones = 26.
Same process! Convert 3 tens to blocks, then subtract: blocks would remain.
Add your answer back to what you removed: . If you get the original number, you're correct!
