What is 4/3 minus 5/7 as a fraction?
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 4/3
Fraction B: 5/7
What to be found?
4/3-5/7 = ?
Find what's the difference between 4/3 and 5/7.
step 2 Compare the denominators of fractions 4/3 and 5/7 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 4/3 and 5/7 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 4/3 and 5/7:
The LCM of 3 and 7 is 21.
step 4 Write the fractions 4/3 and 5/7 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
=4/3-5/7
=(4 x 21)/(3 x 21)-(5 x 21)/(7 x 21)
step 5 Simplify the expression to have common denominator:
=28/21-15/21
step 6 Take the common values out and rewrite the above expression like the below:
=1/21 x (28/1-15/1)
=1/21 x (28 - 15)
step 7Simplify the above expression further:
=1/21 x 13
=13/21
4/3-5/7=13/21
Hence,
4/3 minus 5/7 equals to 13/21 in fraction.
