Question

(4 1/5-а)-(а+5/7)= если а=1 6/35

Answer 1

$(4 \frac{1}{5} -1 \frac{6}{35} )-(1 \frac{6}{35} + \frac{5}{7} )= \frac{147}{35} - \frac{41}{35} - \frac{41}{35}- \frac{25}{35} = \frac{40}{35} = \frac{8}{7} =1 \frac{1}{7}$

Answer 2

To solve this problem, we substitute the value of "a" given as 1 6/35, and simplify the expression using the order of operations (PEMDAS):

(4 1/5 - 1 6/35) - (1 6/35 + 5/7)

= (21/5 - 41/35) - (41/35 + 25/35)

= (147/35 - 41/35) - 66/35

= 106/35 - 66/35

= 40/35

= 8/7

Therefore, the solution is 8/7.
