Subtraction Of Decimals Quiz for students
Learn to subtract numbers involving decimals
Subtraction is a math operation that helps us find the difference between two numbers. When we subtract decimals, we are trying to find how much one number is greater or less than another number.
For example, let’s say we want to subtract 1.25 from 4. We can think of this as asking how much 4 is greater than 1.25. The answer is 2.75 because 4 – 1.25 = 2.75. We can write this as: 4 – 1.25 = 2.75
When subtracting decimals, it’s important to line up the decimal points in the numbers we are subtracting. The decimal point helps us keep track of the ones and tenths, hundredths, and so on places.
For example, let’s subtract 0.8 from 3.2
3.2 -0.8 = 2.4
You can see that decimal points are aligned and we start subtracting right to left, tenth place to tenth place, hundredth place to hundredth place, and so on.
It’s also important to remember to borrow when necessary. Borrowing is a way to subtract larger numbers when we don’t have enough to subtract smaller numbers. For example, when we subtract 0.8 from 3.2, we don’t have 0 in tenth place, so we borrow from whole number place. It change 3.2 to 2.4.
It’s important to note that sometimes when subtracting decimals, we may have to add zeroes to the right of one or both of the decimals to make sure the decimal places are lined up correctly. For example, when we subtract 0.8 from 3.2. We don’t have hundredth place in the number 0.8, so we add 0 to the right of 0.8 making it 0.80.
Another thing to keep in mind is that when subtracting decimals, it’s always a good idea to double check your work by adding the answer to the smaller number to make sure it equals the larger number.
It’s always good to practice with different numbers, using different methods like borrowing and adding zeroes to the right of the decimals when necessary and also to check your work.
With practice and patience, you’ll get better at subtracting decimals in no time!
