2. Cross multiplication method.

(2/7) - (1/90) using LCM Method:
What is 2/7 minus 1/90 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 2/7
Fraction B: 1/90

What to be found?
(2/7) - (1/90) = ?
Find what's the difference between 2/7 and 1/90.

step 2 Compare the denominators of fractions 2/7 and 1/90 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 2/7 and 1/90 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 2/7 and 1/90:
The LCM of 7 and 90 is 630.

step 4 Write the fractions 2/7 and 1/90 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
= 2/7 - 1/90
= [(2 x 630)/(7 x 630)] - [(1 x 630)/(90 x 630)]

step 5 Simplify the expression to have common denominator:
= 180/630 - 7/630

step 6 Take the common values out and rewrite the above expression like the below:
= 1/630 x (180/1 - 7/1)
= 1/630 x (180 - 7)

step 7Simplify the above expression further:
= 1/630 x 173
= 173/630
2/7 - 1/90 = 173/630

Hence,
2/7 minus 1/90 as a fraction is 173/630.
