Question

1,6×(-5,3)-2,4×(-5,3)-4 целых 4/5×5,3=

Answer 1

-8,48+13,72- 24/5 ×53/10
-8,48+12,72- 12/5× 53/5
-8,48+12,72- 636/25
-8,48+12,72-25,44= -21,2 ; -106/5 ; - 21 1/5

Answer 2

Let's break down the given expression step by step:

1. Multiply 1.6 by (-5.3): 1.6 x (-5.3) = -8.48

2. Multiply 2.4 by (-5.3): 2.4 x (-5.3) = -12.72

3. Subtract the result from step 2 from the result from step 1: -8.48 - (-12.72) = 4.24

4. Convert 4 and 4/5 to an improper fraction: 4 + 4/5 = (4 x 5 + 4) / 5 = 24/5

5. Multiply 24/5 by 5.3: 24/5 x 5.3 = 127.2/5

6. Subtract the result from step 3 from the result from step 5: 127.2/5 - 4.24 = 120.96/5

Therefore, the final answer is 120.96/5 or 24.192.
