4/10 -1/5
9/15-1/3
4/12-1/6
find the difference
First you need to find the common denominators and convert one to an equivalent fraction.
4/10 - 2/10
What are the other equivalent fractions?
2/10
To find the difference between fractions, we need to subtract the second fraction from the first fraction. Let's go through each example step by step:
1. 4/10 - 1/5:
To subtract these fractions, we need to have a common denominator. In this case, the lowest common denominator is 10. So, let's convert both fractions with this denominator:
4/10 - 1/5 = (4/10) - (2/10)
Now that the fractions have the same denominator, we can subtract the numerators:
= (4 - 2)/10
= 2/10
Simplifying this fraction gives us the final answer:
= 1/5
2. 9/15 - 1/3:
Again, let's find a common denominator. In this case, the lowest common denominator is 15. So, let's convert both fractions:
9/15 - 1/3 = (9/15) - (5/15)
Now that the fractions have the same denominator, we can subtract the numerators:
= (9 - 5)/15
= 4/15
3. 4/12 - 1/6:
Once more, let's find a common denominator. The lowest common denominator here is 12. So, let's convert both fractions:
4/12 - 1/6 = (4/12) - (2/12)
Now that the fractions have the same denominator, we can subtract the numerators:
= (4 - 2)/12
= 2/12
Simplifying the fraction gives us the final answer:
= 1/6
Therefore, the differences are:
1/5, 4/15, and 1/6, respectively.
