Subtracting whole numbers is different from subtracting the fractions. In a scenario that involves subtraction between two fractions, the arithmetic operation could be performed if and only if the denominators of both the numbers are same. So first the denominators need to be set as same for the fractions and then subtract the numerators. Further simplification might also be required. In this quiz, the child will learn how to subtract and as well as how to deal with fractions. The fractions in the question are nowhere intended to make it complicated and thus it will be easy for the kids to solve.

Learn to subtract fractions

Subtraction of fractions is a method for finding the difference between two fractions. A fraction consists of two parts: a numerator (the top number) and a denominator (the bottom number). To subtract fractions, the denominators (the bottom numbers) must be the same.

For example, to subtract 1/4 from 3/4, we must first make sure that the denominators are the same. In this case, they are already the same, so we can proceed to subtract the numerators (the top numbers). 3/4 – 1/4 = 2/4, which simplifies to 1/2. So the difference between 3/4 and 1/4 is 1/2.

When the denominators are not the same, we have to find a common denominator before we can subtract the numerators. A common denominator is a number that is a multiple of both denominators.

For example, let’s subtract 1/5 from 3/7. To find a common denominator, we can find the least common multiple (LCM) of 5 and 7. The LCM of 5 and 7 is 35. So we can convert both fractions to have a denominator of 35. 3/7 = (35) / (75) = 15/35 and 1/5 = (17)/(57) = 7/35 Now we can subtract the numerators: 15/35 – 7/35 = 8/35

It’s also important to simplify the fraction if it is possible.

For example, 8/35 can be simplified by dividing both the numerator and denominator by the greatest common factor (GCF) which is 1.

So the final answer is 8/35

It’s important to note that the result of subtraction is not always a simplified fraction, it depends on the numerator and denominator.

In summary, to subtract fractions, we first need to find a common denominator and then subtract the numerators. After that, we can simplify the fraction if possible.
