Question

( 7, 6 - четыре целых три четвертых ) : 1, 9

Answer 1

(7 6/10-4 3/4):1 9/10= (152/20-95/20):19/10=57/20:19/10=3/2=1,5

Answer 2

Let's simplify the expression step by step:

First, we need to evaluate the expression inside the parentheses: 6 - четыре целых три четвертых = 6 - 4 3/4 (convert the mixed number to an improper fraction) = 6 - (4*4 + 3)/4 = 6 - 19/4 = (24/4) - (19/4) = 5/4

So now we have: (7, 5/4) : 1, 9

Next, we need to perform the division operation: (7, 5/4) : 1, 9 = (7 + 5/4) / (1 + 9) = (28/4 + 5/4) / 10 = 33/40

Therefore, the final answer is 33/40.
