We built the number 48 - we took out 8 units
How many are left?
To solve this problem, we'll perform a simple arithmetic subtraction, as follows:
Let's carry out the calculation:
Step 1: We start with a total of 48 units.
Step 2: We subtract 8 units from 48.
Step 3: Calculating the subtraction, we find:
This means there are 40 units left after removing 8 units from 48.
Therefore, the solution to the problem is .
If we have 67 blocks in total, how many blocks will remain if we remove 5 tens and 4 ones?
The long rectangles represent tens blocks (each worth 10), and the small squares represent unit blocks (each worth 1). Count 4 tens blocks + 8 unit blocks = 48 total.
It means we subtract 8 from our original number. In the visual, this would be like removing 8 of the small square blocks, leaving us with just the tens blocks.
After removing 8 units from 48, we have 4 complete tens blocks left (and no individual units). Since 4 tens = , the answer is 40.
Use addition to check: . If your subtraction answer plus what you took away equals your starting number, you're correct!
In this problem, we don't need to regroup because we have enough units (8) to subtract directly. When you need more units, you'd break apart one tens block into 10 units first.
