Answer 2

Пошаговое объяснение:

а)

4/5 - 1/2 - 1/6 = 24/30 - 15/30 - 5/30 =

(24-15-5)/30 = 4/30 = 2/15

б)

5/6 - 2/5 - 1/7 = 175/210 - 84/210 - 30/210 =

(175-84-30)/210 = 61/210

Answer 3

a) 4/5 - 1/2 - 1/6 First, find a common denominator, which in this case would be 30. Then convert each fraction to have the common denominator: 4/5 = 24/30 1/2 = 15/30 1/6 = 5/30 Now, subtract the fractions: 24/30 - 15/30 - 5/30 = 4/30 Simplify the result: 4/30 = 2/15 So, the result of a) is 2/15.

b) 5/6 - 2/5 - 1/7 Again, find a common denominator, which in this case would be 210. Then convert each fraction to have the common denominator: 5/6 = 35/42 2/5 = 84/210 1/7 = 30/210 Now, subtract the fractions: 35/42 - 84/210 - 30/210 = 35/42 - 114/210 To subtract these fractions, you need to find a common denominator, which is 210. Then subtract the numerators: 35/42 - 114/210 = 175/210 - 114/210 = 61/210 So, the result of b) is 61/210.
