Introduction to practice subtracting fractions:
To practice subtracting fractions, first we convert both denominators to the number. Fractions are reduced to their lowest terms so that they would be easier to recognize. To find fraction’s lowest terms, you need to divide the numerator and the denominator by anycommon factors. Here we need to practice subtracting fractions that is learning subtracting fractions problems. In this article let us see problems to practice subtracting fractions.
Practice Subtracting Fractions:
Subtracting fractions is a process of collecting all like fractions. If the denominators are the same then just subtract the numerators.
Example 1:
`9/ 8` - `4/ 8`
Solution:
If the denominators are the same then just subtract the numerators.
`9/ 8` - `4/ 8` = `5/8`
Example 2:
`1/3` - `2/5`
Solution:
If the denominators are different then first find the LCM of denominator and make the denominator same then subtract the numerator.
`1/3` - `2/5` LCM = 15 ie. Both 3 and 5 of denominator is multiple of 15.
`1/3` - `2/5` = `(1*5) / (3*5)` - `(2*3)/(5*3)` = `5/15` - `6/15` = `-1/15` .
Example 3:
`11/ 8` - `4/ 8`
Solution:
If the denominators are the same then just subtract the numerators.
`11/ 8` - `4/ 8` = `7/8`
Example 4:
`1/3` - `1/4`
Solution:
If the denominators are different then first find the LCM of denominator and make the denominator same then subtract the numerator.
`1/3` - `1/4` LCM = 12 ie. Both 3 and 4 of denominator is multiple of 12.
`1/3` - `1/4` = `(1*4) / (3*4)` - `(1*3)/(4*3)` = `4/12` - `3/12` = `1/12` .

Example 5:
`12/ 8` - `5/ 8`
Solution:
If the denominators are the same then just subtract the numerators.
`12/ 8` - `5/ 8` = `7/8`
Example 6:
`12/7` - `1/8`
Solution:
If the denominators are different then first find the LCM of denominator and make the denominator same then subtract the numerator.Please express your views of this topic Free math problem solver by commenting on blog.
`12/2` - `1/8` LCM = 8 ie. Both 2 and 8 of denominator is multiple of 8.
`12/2` - `1/8` = `(12*4) / (2*4)` - `1/ 8` = `48/8` - `1/8` = `47/8` .
Example 7:
`18/ 8` - `9/ 8`
Solution:
If the denominators are the same then just subtract the numerators.
`18/ 8` - `9/ 8` = `9/8`
Example 8:
`4/3` - `2/5`
Solution:
If the denominators are different then first find the LCM of denominator and make the denominator same then subtract the numerator.
`4/3` - `2/5` LCM = 15 ie. Both 3 and 5 of denominator is multiple of 15.
`4/3` - `2/5` = `(4*5) / (3*5)` - `2/15` = `20/15` - `2/15` = `18/15` .
