Answer:

2(1/5)

Step-by-step explanation:

7(1/5) - 3(11/5)

= {(35 + 1)/5} - {(14+11)/5}

= (36/5) - (25/5)

Take the LCM of the denominator 5 and 5 is 5 as common.

= (36*1 - 25*1)/5

= (36 - 25)/5

= 11/5

= 2(1/5) → [Mixed fraction] Ans.

Please let me know if you have any other questions.

We must find the common denominator.

5 goes into 15, but to get 5 to 15, we must multiply by 3. When doing this, we have to multiply the numerator by the same thing.

1 x 3 = 3
5 x 3 = 15

3/15 is the new fraction. Because we’re subtracting, it would be easier to convert the mixed number (7 3/15) into an improper fraction. 7 x 15 = 105 + 3 = 108. 108/15 is the improper fraction. 3 x 15 = 45 + 11 = 46. 46/11 is the other improper fraction.

108 - 46 = 62.

62/15 = 4 2/15.

4 2/15 is the final answer.
