=7/10-8/10

step 6 Take the common values out and rewrite the above expression like the below:
=1/10 x (7/1-8/1)
=1/10 x (7 - 8)

step 7Simplify the above expression further:
=1/10 x -1
=-1/10
7/10-4/5=-1/10

Input:
Fraction A: 7/10
Fraction B: 4/5

What to be found?
7/10-4/5 = ?
Find what's the difference between 7/10 and 4/5.

step 2 Find the product of numerator of Fraction A and denominator of Fraction B (7 x 5), find the product of numerator of Fraction B and denominator of Fraction A (4 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:
= (7 x 5) - (4 x 10)/(10 x 5)

step 3 Simplify and rewrite the fraction:
= (35 - 40)/50
= -5/50
= -1/10
