Answer:
4/5
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
