Ответ: 5,6.

Пошаговое объяснение:

$\frac{12}{10} *\frac{5}{6} +\frac{69}{10} *\frac{2}{3} =\frac{2}{2} *\frac{1}{1} +\frac{23}{5} *\frac{1}{1}=1+4\frac{3}{5} =5\frac{3}{5} =5\frac{6}{10} =5,6$

Answer 3

To solve this expression, you'll need to perform the multiplications and additions in the correct order, following the standard rules of arithmetic (PEMDAS/BODMAS).

Here's the step-by-step calculation:

1. First, perform the multiplications:

   • 1.2 * 5/6 = 6/5
   • 6.9 * 2/3 = 4.6

2. Now, add the results of the multiplications:

   • 6/5 + 4.6

3. To add these two numbers, you'll need to find a common denominator. In this case, you can convert 4.6 to a fraction with a denominator of 5:

   • 4.6 = 4.6 * 5/5 = 23/5

4. Now, you can add the fractions:

   • 6/5 + 23/5 = (6 + 23) / 5 = 29/5

So, the final result is 29/5. If you prefer a decimal answer, you can convert the fraction to a decimal:

29/5 = 5.8

So, 1.2 * 5/6 + 6.9 * 2/3 = 5.8
