2. Cross multiplication method.
11/7-7 using LCM Method:
What is 11/7 minus 7 as a fraction?
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 11/7
Fraction B: 7/1
What to be found?
11/7-7 = ?
Find what's the difference between 11/7 and 7.
step 2 Compare the denominators of fractions 11/7 and 7 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 11/7 and 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 11/7 and 7:
The LCM of 7 and 1 is 7.
step 4 Write the fractions 11/7 and 7 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
=11/7-7
=(11 x 7)/(7 x 7)-(7 x 7)/(1 x 7)
step 5 Simplify the expression to have common denominator:
=11/7-49/7
step 6 Take the common values out and rewrite the above expression like the below:
=1/7 x (11/1-49/1)
=1/7 x (11 - 49)
step 7Simplify the above expression further:
=1/7 x -38
=-38/7
11/7-7=-38/7
Hence,
11/7 minus 7 equals to -38/7 in fraction.
11/7-7 using Cross Multiplication Method:
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 11/7
Fraction B: 7/1
What to be found?
11/7-7 = ?
Find what's the difference between 11/7 and 7.
step 2 Find the product of numerator of Fraction A and denominator of Fraction B (11 x 1), find the product of numerator of Fraction B and denominator of Fraction A (7 x 7), and find the product of both denominators of Fraction A and Fraction B (7 x 1) and rewrite the equation as like the below:
= (11 x 1) - (7 x 7)/(7 x 1)
step 3 Simplify and rewrite the fraction:
= (11 - 49)/7
11/7-7 = -38/7
Hence,
11/7 minus 7 = -38/7
