Answer 1

Ответ:

29/10 или 2 9/10

Пошаговое объяснение:

1) 17 16/19-5 16/19=339/19-111/19=225/19

2) 7 3/5-4 4/5= 38/5-24/5=14/5

3) 30÷225/19=30×19/225=38/15=2 8/15

4) 14/5÷7=14/5÷7/1=14/5×1/7=2/5

5) 38/15+2/5=38/15+6/15=44/15

Answer 2

It looks like you've provided a mathematical expression that needs to be simplified. Let's break down the expression step by step:

1. Calculate the values inside the parentheses first:

   • $17 \frac{16}{19} - 5 \frac{16}{19} = 11 \frac{16}{19}$
   • $7 \frac{3}{5} - 4 \frac{4}{5} = 2 \frac{1}{5}$

2. Combine the results from the parentheses:

   • $11 \frac{16}{19} + 2 \frac{1}{5} = 13 \frac{37}{95}$

3. Finally, perform the division:

   • $\frac{13 \frac{37}{95}}{7} = 1 \frac{84}{665}$

So, the simplified value of the given expression is $1 \frac{84}{665}$.
