Answer:

-41/20

Explanation:

Hi there!

From the question, I believe you’re asking
(3)/(4) -
2 (4)/(5)

First, put the whole number 2 back into the fraction to create an improper fraction.

This would become
(14)/(5). Now, we have to find a common denominator between the two fractions. Both 4 and 5 can go into 20, so that will be our common denominator. To turn
(3)/(4) into a fraction with a denominator of 20, we have to multiply both the numerator and denominator by 5.
(3)/(4) becomes
(15)/(20). We do the same thing for
(14)/(5) except we multiply the numerator and denominator by 4. We end up with
(56)/(20). Now we just have to subtract!


(15)/(20) - (56)/(20) leaves us with
- (41)/(20) , which can’t be simplified any further.
