Question

3/7 (-0,54) - 1,56 х 3/7

Answer 1

3/7(-27/50)-39/25x3/7
-81/350-117/175
-9/10
-0,9

Answer 2

To solve the expression, let's perform the calculations step by step:

1. Evaluate -0.54 times 3/7: -0.54 * (3/7) = -0.54 * 3 / 7 = -1.62 / 7

2. Subtract 1.56 times 3/7 from the result obtained in step 1: (-1.62 / 7) - (1.56 * 3/7) = -1.62 / 7 - (1.56 * 3 / 7) = -1.62 / 7 - 4.68 / 7

3. Combine the fractions with a common denominator (7): (-1.62 - 4.68) / 7 = -6.30 / 7

So, the final result of the expression is: -6.30 / 7.
