Answer 1

Вот, надеюсь правильно

Answer 2

To calculate the expression, we'll follow the order of operations (PEMDAS/BODMAS). Here's the step-by-step solution:

1. Convert the mixed numbers to improper fractions:

   • 5 1/3 = (3 * 5 + 1) / 3 = 16/3
   • 2 3/4 = (4 * 2 + 3) / 4 = 11/4
   • 5 1/3 = (3 * 5 + 1) / 3 = 16/3
   • 7 1/2 = (2 * 7 + 1) / 2 = 15/2
   • 1 1/9 = (9 * 1 + 1) / 9 = 10/9

2. Perform the multiplications first:

   • (16/3) * 9 = 144/3 = 48
   • (11/4) * (16/3) = (11 * 16) / (4 * 3) = 176/12 = 44/3
   • (15/2) * (10/9) = (15 * 10) / (2 * 9) = 150/18 = 25/3

3. Perform the subtractions:

   • 48 - (44/3) = (48 * 3) / 3 - (44/3) = 144/3 - 44/3 = 100/3
   • (100/3) - (25/3) = 100/3 - 25/3 = 75/3 = 25

Therefore, the result of the expression 5 1/3 * 9 - 2 3/4 * 5 1/3 - 7 1/2 * 1 1/9 is 25.
