6th grade Q1
Let’s see how you can solve 1-step problems involving subtraction of decimals.
Example:
A bucket held 12.8 liters of water, but 7.35 liters spilled out. How much water is left in the bucket?
Step 1: Understand the problem
You are asked to find how much water is left. This means you need to subtract the amount that spilled from the total amount:
Step 2: Line up the decimal points
Write the numbers so the decimal points are aligned. Add a zero to the first number to ensure both have the same number of decimal places:
Step 3: Subtract each column from right to left
Start with the smallest place value, the hundredths place. 0 is less than 5, so you need to borrow 1 from the tenths place, so 0 becomes 10.
Then move to the tenths place. You've borrowed 1 form the tenths place, so you're left with 7.
Next, subtract the ones place. Borrow 1 from the tens place. 2 becomes 12.
Finally, subtract the tens place. You've borrowed 1 from the tens place, so you're left with 0.
Step 4: Write the final answer
You can remove the 0 in the tens place as that doesn't change the value of the number.
Final Answer:
There are 5.45 liters of water left in the bucket.
