3/9-8/11 using LCM Method:
What is 3/9 minus 8/11 as a fraction?
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 3/9
Fraction B: 8/11
What to be found?
3/9-8/11 = ?
Find what's the difference between 3/9 and 8/11.
step 2 Compare the denominators of fractions 3/9 and 8/11 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 3/9 and 8/11 are not equal, it is said to be unlike fractions subtraction.
step 3For unlike fractions subtraction, find the LCM (least common multiple) of both denominators of fractions 3/9 and 8/11:
The LCM of 9 and 11 is 99.
step 4 Write the fractions 3/9 and 8/11 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
=3/9-8/11
=(3 x 99)/(9 x 99)-(8 x 99)/(11 x 99)
step 5 Simplify the expression to have common denominator:
=33/99-72/99
step 6 Take the common values out and rewrite the above expression like the below:
=1/99 x (33/1-72/1)
=1/99 x (33 - 72)
step 7Simplify the above expression further:
=1/99 x -39
= -39/99
=-13/33
3/9-8/11=-13/33
Hence,
3/9 minus 8/11 equals to -13/33 in fraction.
3/9-8/11 using Cross Multiplication Method:
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 3/9
Fraction B: 8/11
What to be found?
3/9-8/11 = ?
Find what's the difference between 3/9 and 8/11.
step 2 Find the product of numerator of Fraction A and denominator of Fraction B (3 x 11), find the product of numerator of Fraction B and denominator of Fraction A (8 x 9), and find the product of both denominators of Fraction A and Fraction B (9 x 11) and rewrite the equation as like the below:
= (3 x 11) - (8 x 9)/(9 x 11)
step 3 Simplify and rewrite the fraction:
= (33 - 72)/99
= -39/99
= -13/33
3/9-8/11 = -13/33
Hence,
3/9 minus 8/11 = -13/33
