Question

8 7/10-(7 4/5-а) при а =6 1/2

Answer 1

1)7 4/5-6 1/2=1 3/10
2)8 7/10-1 3/10=7 2/5

Answer 2

To solve this problem, we first need to substitute the value of a=6 1/2 in the given expression:

8 7/10 - (7 4/5 - 6 1/2) = 8 7/10 - (7 4/5 - 12/2) = 8 7/10 - (7 4/5 - 6) = 8 7/10 - 1 4/5 = 7 3/10

Therefore, the value of the expression 8 7/10 - (7 4/5 - а) when а=6 1/2 is 7 3/10.
