Question

(-1/8+1/5)-(4,8-4,9)-2,05=?​

Answer 1

1) в скобках (-1/8+1/5) = 0.075

2) в скобках ( 4,8 - 4,9) = -0.1

3 0.075 - 0.1 = 0.175

4 0.175 - 2,05 = -1.875

Answer 2

((-0,125)+0,2)-(4,8-4,9)-2,05=-1,875

Answer 3

Let's break down the expression step by step:

1. Start with (-1/8 + 1/5): (-1/8 + 1/5) can be simplified by finding a common denominator, which is 40 in this case. So:

   (-1/8 * 5/5 + 1/5 * 8/8) = (-5/40 + 8/40)

   Now, add the fractions with the common denominator:

   (-5/40 + 8/40) = (3/40)

2. Next, subtract (4.8 - 4.9): (4.8 - 4.9) = -0.1

3. Finally, subtract 2.05 from the result obtained in step 1: (3/40) - 2.05

To subtract a fraction from a decimal, you'll want to convert the fraction to a decimal with the same number of decimal places as the other number. In this case, you can convert 3/40 to a decimal by dividing 3 by 40:

3/40 ≈ 0.075

Now, subtract 0.075 from 2.05:

2.05 - 0.075 = 1.975

So, the final result is approximately 1.975.
