On the shelf in the supermarket warehouse, there are 64 milk cartons.
The supermarket's workers arranged took 4 boxes of 10 milk cartons each.
How many milk cartons are left on the warehouse shelf?
To solve this problem, we'll follow these steps:
Here's how we do it:
Step 1: Calculate the total milk cartons taken away. The problem states that 4 boxes of 10 cartons each were removed:
Step 2: Subtract the removed cartons from the initial total of 64:
Step 3: Compare with choices, and we see that 24 is indeed one of the choices provided (Choice 2).
Therefore, the number of milk cartons left on the warehouse shelf is .
If we have 67 blocks in total, how many blocks will remain if we remove 5 tens and 4 ones?
Because 4 represents the number of boxes, not individual cartons! Each box contains 10 cartons, so you need to calculate cartons total before subtracting.
Look for groups or containers in the problem. When you see phrases like '4 boxes of 10 each' or '3 packs of 5 each', always multiply to find the total before adding or subtracting.
Calculate each group separately first! For example: 3 boxes of 10 plus 2 boxes of 15 means total items.
Use estimation! In this problem, we removed about 40 cartons from 64, so the answer should be around 20-25. The answer 24 fits perfectly!
Don't worry! Always re-read the problem and ask yourself: 'Am I working with individual items or groups of items?' This helps catch multiplication mistakes before they happen.
Yes! You could think of it as: , subtracting each box one at a time. Both methods give the same answer!
