Question

(0.28+1 1/3):11/30=​

Answer 1

(0.28+1 1/3):11/30

1) 0.28 переводим в обыкновенную дробь = 28/100

2)2/100+1 1/3 =2/100 + 4/3=2/100×3 + 4/3 × 100 =406/300=1 106/300

3)1 106/300:11/30= 406/110=3 76/110

Answer 2

Ответ:10,7

Пошаговое объяснение:

1. 11:3=3,6.

2. 0,28+3,6=3,88.

3. 11:30=0.36.

4. 3,88:0,36=10,7

Answer 3

To solve the expression, first, we need to convert the mixed number (1 1/3) into an improper fraction:

1 1/3 = (3 * 1 + 1)/3 = 4/3

Now, we can rewrite the expression as follows:

(0.28 + 4/3) / 11/30

Next, we need to find a common denominator for the fractions in the numerator:

The common denominator for 0.28 and 4/3 is 3. So, we convert 0.28 into a fraction with a denominator of 3:

0.28 = 28/100 = 14/50 = 56/200

Now, the expression becomes:

(56/200 + 4/3) / 11/30

To add these fractions, we need a common denominator, which is 3 * 200 = 600:

(56/200 * 3/3 + 4/3 * 200/200) / 11/30 = (168/600 + 800/600) / 11/30 = (968/600) / 11/30

Now, to divide fractions, we can invert the second fraction and multiply:

= (968/600) * (30/11) = (8/5) * (30/11) = 240/55 = 48/11 or approximately 4.3636

So, (0.28 + 1 1/3) / 11/30 is approximately equal to 4.3636 or 48/11.
