Пошаговое объяснение:

15/16 ·3 3/5 -7 7/8=3/16 ·18-7 7/8=27/8 -7 7/8=3 3/8 -7 7/8=-4 1/2=-4,5

8,3 -1,33/3,4=8,3 -13,3/34=(282,2 -13,3)/34=2689/340=7 309/340

Answer 2

To solve the given expressions, let's break them down step by step:

1. 15/16 * 3: Multiply the numerator (15) by the denominator (3) and divide the result by the denominator (16): (15 * 3) / 16 = 45 / 16

2. 3/5 - 7: Subtract 7 from the fraction 3/5: 3/5 - 7 = 3/5 - (7 * 5/5) = 3/5 - 35/5 = (3 - 35) / 5 = -32/5

3. 7/8: This is already a simplified fraction, so no further calculations are needed.

4. 8.3 - 1.33 / 3.4: First, perform the division 1.33 / 3.4, then subtract the result from 8.3: 8.3 - (1.33 / 3.4) = 8.3 - 0.391176 = 7.908824

So, the simplified values are:

1. 45/16
2. -32/5
3. 7/8
4. 7.908824
