7 1/5 - 6 2/5=

a. 1 1/5

b. 1 4/5

c. 13 3/5

d. 4/5

4/5

Step-by-step explanation:

Simplify the following:

7 + 1/5 - (6 + 2/5)

Put 6 + 2/5 over the common denominator 5. 6 + 2/5 = (5*6) / 5 + 2/5:

7 + 1/5 - (5*6) / 5 + 2/5

5*6 = 30:

7 + 1/5 - (30/5 + 2/5)

30/5 + 2/5 = (30 + 2) / 5:

7 + 1/5 - (30 + 2) / 5

30 + 2 = 32:

7 + 1/5 - 32/5

Put 7 + 1/5 - 32/5 over the common denominator 5. 7 + 1/5 - 32/5 = (5*7) / 5 + 1/5 - 32/5:

(5*7) / 5 + 1/5 - 32/5

5*7 = 35:

35/5 + 1/5 - 32/5

35/5 + 1/5 - 32/5 = (35 + 1 - 32) / 5:

(35 + 1 - 32) / 5

35 + 1 = 36:

(36 - 32) / 5
