2. Cross multiplication method.

(1/5) - (15/14) using LCM Method:
What is 1/5 minus 15/14 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 1/5
Fraction B: 15/14

What to be found?
(1/5) - (15/14) = ?
Find what's the difference between 1/5 and 15/14.

step 2 Compare the denominators of fractions 1/5 and 15/14 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 1/5 and 15/14 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 1/5 and 15/14:
The LCM of 5 and 14 is 70.

step 4 Write the fractions 1/5 and 15/14 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
= 1/5 - 15/14
= [(1 x 70)/(5 x 70)] - [(15 x 70)/(14 x 70)]

step 5 Simplify the expression to have common denominator:
= 14/70 - 75/70

step 6 Take the common values out and rewrite the above expression like the below:
= 1/70 x (14/1 - 75/1)
= 1/70 x (14 - 75)

step 7Simplify the above expression further:
= 1/70 x -61
= -61/70
1/5 - 15/14 = -61/70

Hence,
1/5 minus 15/14 as a fraction is -61/70.
