Question

0,3 + 0,029 : (6/35 – 0,13) = 6/35 - это обыкновенная дробь (числитель и знаменатель)

Answer 1

1) 6/35-13/100=600/3500-455/3500=145/3500=29/700

2)29/1000:29/700=700/1000=0,7

3)0,7+0,3=1

Answer 2

To simplify the expression, let's first work on the numerator and denominator of the fraction separately.

Numerator: 0.3 + 0.029 The sum of 0.3 and 0.029 is 0.329.

Denominator: (6/35 - 0.13) To subtract fractions, we need to find a common denominator. The common denominator for 35 and 1 is 35.

6/35 - 0.13 (as an improper fraction) = 6/35 - 0.13 * (35/35) = 6/35 - 4.55/35 = (6 - 4.55)/35 = 1.45/35

Now, let's substitute these values back into the original expression:

0.329 / (1.45/35)

To divide by a fraction, we can multiply by its reciprocal:

0.329 * (35/1.45)

Calculating this expression gives us:

0.329 * (35/1.45) ≈ 7.947

Therefore, the result of the expression is approximately 7.947.
