Question

А) 2- 1/5 б)6- 1/6 в) 4-3/4 г) 3-4/7

Answer 1

a) 2 - 1/5 = 2/1 -1/5 (дополнительные множители 5 и 1). 10/5 - 1/5 = 9/5

б) 6 - 1/6 = 6/1 - 1/6 (дополнительные множители 6 и 1) = 36/6 - 1/6 = 35/6

в) 4 - 3/4 = 4/1 - 3/4 (дополнительные множители 4 и 1) = 16/4 - 3/4 = 12/4

г) 3 - 4/7 = 3/1 - 4/7 (дополнительные множители  7 и 1) = 21/7 - 4/7 = 17/7

Answer 2

а) 2- 1/5=1,8

б)6- 1/6=5,8(3)

в) 4-3/4=3,25

г) 3-4/7=2,42

Answer 3

To simplify the expressions, let's calculate the values:

а) 2 - 1/5 To subtract fractions, the denominators must be the same. So, convert 2 to a fraction with a denominator of 5: 2 = 10/5 Now, subtract the fractions: 10/5 - 1/5 = (10 - 1)/5 = 9/5

b) 6 - 1/6 Convert 6 to a fraction with a denominator of 6: 6 = 36/6 Now, subtract the fractions: 36/6 - 1/6 = (36 - 1)/6 = 35/6

c) 4 - 3/4 Convert 4 to a fraction with a denominator of 4: 4 = 16/4 Now, subtract the fractions: 16/4 - 3/4 = (16 - 3)/4 = 13/4

d) 3 - 4/7 Convert 3 to a fraction with a denominator of 7: 3 = 21/7 Now, subtract the fractions: 21/7 - 4/7 = (21 - 4)/7 = 17/7

So, the simplified expressions are: а) 2 - 1/5 = 9/5 b) 6 - 1/6 = 35/6 c) 4 - 3/4 = 13/4 d) 3 - 4/7 = 17/7
