Question

0,5 + 8/9и5 1/3 + 4,5​

Answer 1

Ответ:

1) 1 7/18.

2) 9 5/6.

Пошаговое объяснение:

0,5 + 8/9 = 5/10 + 8/9 = 1/2 + 8/9 = 9/18 + 16/18 = 25/18 = 1 7/18.

5 1/3 + 4,5 = 5 1/3 + 4 1/2 = 5 2/6 + 4 3/6 = 9 5/6.

Answer 2

It appears you've written a mathematical expression using both decimal numbers and mixed fractions. Let's break it down step by step:

1. 0.5 + 8/9 First, add the decimal number and the fraction: 0.5 + 8/9 = (0.5 * 9/9) + 8/9 = 4.5/9 + 8/9

   Now, add the fractions: (4.5 + 8) / 9 = 12.5 / 9

2. 5 1/3 + 4.5 To add a mixed fraction to a decimal number, first convert the mixed fraction to an improper fraction: 5 1/3 = (5 * 3 + 1) / 3 = 16/3

   Now, add the improper fraction and the decimal number: 16/3 + 4.5

To add these two results, you need a common denominator, which in this case is 3:

(12.5/9) + (16/3)

To add fractions with a common denominator, you simply add their numerators:

[(12.5 + 48)/9] / 3

Now, add the numerators:

(60.5/9) / 3

To divide by 3, you can multiply by its reciprocal, which is 1/3:

(60.5/9) * (1/3)

Now, multiply the numerators and denominators:

(60.5 * 1) / (9 * 3)

This simplifies to:

60.5 / 27

To simplify further, you can divide both the numerator and denominator by their greatest common divisor, which is 1:

60.5 / 27 ≈ 2.24 (rounded to two decimal places)

So, the result of the expression is approximately 2.24.
