Question

0,15-0,15×6,4/-3/8+0,175

Answer 1

0,15-0,15*6,4-3/8+0,175

0,15-0,96-3/8+0,175

0,15-0,96-0,375+0,175=-1,01

Answer 2

Let's solve the expression step by step:

1. First, perform the multiplication and division from left to right:

0.15 - 0.15 × 6.4 / (-3/8) + 0.175

0.15 - (0.15 × 6.4) / (-3/8) + 0.175

2. Calculate 0.15 × 6.4:

0.15 × 6.4 = 0.96

3. Now, we need to deal with the division. The division of a fraction is the same as multiplying by its reciprocal. The reciprocal of -3/8 is -8/3:

(0.96) / (-3/8) = (0.96) × (-8/3)

4. Calculate (0.96) × (-8/3):

(0.96) × (-8/3) = -2.56

5. Now, we can replace the multiplication and division with the result from the previous step:

0.15 - (-2.56) + 0.175

6. Next, perform the subtraction:

0.15 + 2.56 + 0.175

7. Finally, add the numbers together:

0.15 + 2.56 + 0.175 = 2.885

So, the value of the expression is approximately 2.885.
