2. Cross multiplication method.
5/7-7/16 using LCM Method:
What is 5/7 minus 7/16 as a fraction?
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 5/7
Fraction B: 7/16
What to be found?
5/7-7/16 = ?
Find what's the difference between 5/7 and 7/16.
step 2 Compare the denominators of fractions 5/7 and 7/16 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 5/7 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 5/7 and 7/16:
The LCM of 7 and 16 is 112.
step 4 Write the fractions 5/7 and 7/16 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
=5/7-7/16
=(5 x 112)/(7 x 112)-(7 x 112)/(16 x 112)
step 5 Simplify the expression to have common denominator:
=80/112-49/112
step 6 Take the common values out and rewrite the above expression like the below:
=1/112 x (80/1-49/1)
=1/112 x (80 - 49)
step 7Simplify the above expression further:
=1/112 x 31
=31/112
5/7-7/16=31/112
Hence,
5/7 minus 7/16 equals to 31/112 in fraction.
