Question

(-3.2:0.8*(-0,35)):(-0.3*2.5--0,7*2.5)​

Answer 1

Ответ:

(3,2:0,8*(-0,35)):(_0,3*2,5-0,7*2,5)= - 1,4

Answer 2

To solve the expression:

(-3.2:0.8*(-0.35))/(-0.32.5-(-0.72.5))

First, let's simplify each part step by step:

1. Start with the numerator:

   -3.2 divided by 0.8 times -0.35:

   = (-3.2 / 0.8) * (-0.35)

   Now, solve the numerator:

   = -4 * (-0.35)

   = 1.4

2. Now, move to the denominator:

   -0.3 times 2.5 minus (-0.7 times 2.5):

   = (-0.3 * 2.5) - (-0.7 * 2.5)

   = (-0.75) - (-1.75)

   When you subtract a negative, it's the same as adding the positive:

   = (-0.75) + 1.75

   = 1.75 - 0.75

   = 1

Now, you have the simplified expression:

1.4 / 1

Since any number divided by 1 is itself, the final result is:

1.4
