1. LCM method
2. Cross multiplication method.
(13/9) - (16/15) using LCM Method:
What is 13/9 minus 16/15 as a fraction?
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 13/9
Fraction B: 16/15
What to be found?
(13/9) - (16/15) = ?
Find what's the difference between 13/9 and 16/15.
step 2 Compare the denominators of fractions 13/9 and 16/15 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 13/9 and 16/15 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 13/9 and 16/15:
The LCM of 9 and 15 is 45.
step 4 Write the fractions 13/9 and 16/15 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
= 13/9 - 16/15
= [(13 x 45)/(9 x 45)] - [(16 x 45)/(15 x 45)]
step 5 Simplify the expression to have common denominator:
= 65/45 - 48/45
step 6 Take the common values out and rewrite the above expression like the below:
= 1/45 x (65/1 - 48/1)
= 1/45 x (65 - 48)
step 7Simplify the above expression further:
= 1/45 x 17
= 17/45
13/9 - 16/15 = 17/45
Hence,
13/9 minus 16/15 as a fraction is 17/45.
13/9 - 16/15 using Cross Multiplication Method:
step 1 Observe the input parameters and what to be found:

Fraction B: 16/15
What to be found?
(13/9)-(16/15) = ?
Find what's the difference between 13/9 and 16/15.
step 2 Find the product of numerator of Fraction A and denominator of Fraction B (13 x 15), find the product of numerator of Fraction B and denominator of Fraction A (16 x 9), and find the product of both denominators of Fraction A and Fraction B (9 x 15) and rewrite the equation as like the below:
= (13 x 15) - (16 x 9)/(9 x 15)
step 3 Simplify and rewrite the fraction:
= (195 - 144)/135
= 51/135
= 17/45
