2. Cross multiplication method.

(1/7) - (7/16) using LCM Method:
What is 1/7 minus 7/16 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 1/7
Fraction B: 7/16

What to be found?
(1/7) - (7/16) = ?
Find what's the difference between 1/7 and 7/16.

step 2 Compare the denominators of fractions 1/7 and 7/16 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 1/7 and 7/16 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 1/7 and 7/16:
The LCM of 7 and 16 is 112.

step 4 Write the fractions 1/7 and 7/16 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
= 1/7 - 7/16
= [(1 x 112)/(7 x 112)] - [(7 x 112)/(16 x 112)]

step 5 Simplify the expression to have common denominator:
= 16/112 - 49/112

step 6 Take the common values out and rewrite the above expression like the below:
= 1/112 x (16/1 - 49/1)
= 1/112 x (16 - 49)

step 7Simplify the above expression further:
= 1/112 x -33
= -33/112
1/7 - 7/16 = -33/112

Hence,
1/7 minus 7/16 as a fraction is -33/112.
