What is 9/10 minus 1/5 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 9/10
Fraction B: 1/5

What to be found?
9/10-1/5 = ?
Find what's the difference between 9/10 and 1/5.

step 2 Compare the denominators of fractions 9/10 and 1/5 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 9/10 and 1/5 are not equal, it is said to be unlike fractions subtraction.

The LCM of 10 and 5 is 10.

step 4 Write the fractions 9/10 and 1/5 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
=9/10-1/5
=(9 x 10)/(10 x 10)-(1 x 10)/(5 x 10)

step 5 Simplify the expression to have common denominator:
=9/10-2/10

step 6 Take the common values out and rewrite the above expression like the below:
=1/10 x (9/1-2/1)
=1/10 x (9 - 2)

step 7Simplify the above expression further:
=1/10 x 7
=7/10
9/10-1/5=7/10

Hence,
9/10 minus 1/5 equals to 7/10 in fraction.

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 9/10
Fraction B: 1/5

What to be found?
9/10-1/5 = ?
Find what's the difference between 9/10 and 1/5.

step 2 Find the product of numerator of Fraction A and denominator of Fraction B (9 x 5), find the product of numerator of Fraction B and denominator of Fraction A (1 x 10), and find the product of both denominators of Fraction A and Fraction B (10 x 5) and rewrite the equation as like the below:
= (9 x 5) - (1 x 10)/(10 x 5)

step 3 Simplify and rewrite the fraction:
= (45 - 10)/50
= 35/50
= 7/10
9/10-1/5 = 7/10
Hence,
9/10 minus 1/5 = 7/10
