1/2-12/17 using LCM Method:
What is 1/2 minus 12/17 as a fraction?
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 1/2
Fraction B: 12/17
What to be found?
1/2-12/17 = ?
Find what's the difference between 1/2 and 12/17.
step 2 Compare the denominators of fractions 1/2 and 12/17 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 1/2 and 12/17 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 1/2 and 12/17:
The LCM of 2 and 17 is 34.
step 4 Write the fractions 1/2 and 12/17 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
=1/2-12/17
=(1 x 34)/(2 x 34)-(12 x 34)/(17 x 34)
step 5 Simplify the expression to have common denominator:
=17/34-24/34
step 6 Take the common values out and rewrite the above expression like the below:
=1/34 x (17/1-24/1)
=1/34 x (17 - 24)
step 7Simplify the above expression further:
=1/34 x -7
=-7/34
1/2-12/17=-7/34
Hence,
1/2 minus 12/17 equals to -7/34 in fraction.
