−(3,72−6 4/9)−(0,28−2 5/9). плиииииз ток быстрее даю макс балов

Answer 1

-(93/25 - 58/9) - (7/25 - 23/9) = -( -613/225) - ( -512/225) = 613/225 + 512/225 = 5

Answer 2

−(3,72−6 4/9)−(0,28−2 5/9)=−3,72+6 4/9−0,28+2 5/9=−3,72−0,28+6 4/9+2 5/9=−4+9=9-4=5

Answer 3

To simplify the expression, let's first convert the mixed numbers to improper fractions:

72 - 6 4/9 = 72 - (6 + 4/9) = 72 - (54/9 + 4/9) = 72 - 58/9

28 - 2 5/9 = 28 - (2 + 5/9) = 28 - (18/9 + 5/9) = 28 - 23/9

Now, let's continue simplifying the expression:

-(3, 72 - 6 4/9) - (0, 28 - 2 5/9) = -(3, 72 - 58/9) - (0, 28 - 23/9)

Next, we need to convert the whole numbers to fractions:

3 = 3/1 0 = 0/1

Now, we can rewrite the expression as:

-(3/1 + 72 - 58/9) - (0/1 + 28 - 23/9)

Now, let's find common denominators and simplify further:

Common denominator for 1 and 9 is 9.

= -(27/9 + 648/9 - 58/9) - (0/1 + 252/9 - 23/9)

Now, combine like terms:

= -((27 + 648 - 58)/9) - ((0 + 252 - 23)/9)

= -((675)/9) - ((229)/9)

Now, subtract the fractions:

= -(675/9) - (229/9)

To subtract the fractions, they must have the same denominator:

= -(675 + 229)/9

Now, perform the subtraction:

= -(904)/9

Finally, we can simplify the fraction:

= -100 4/9

So, the simplified expression is -100 4/9.
