Question

4/3+(5/1/2 +5/4умножить 3/1/5):9/10​

Answer 1

Ответ:

Пошаговое объяснение:

4/3+(5/1/2 +5/4*3/1/5):9/10=11 8/9

5/4*3 1/5=5/4*16/5=4

5 1/2+4=9 1/2

9 1/2:9/10=19/2*10/9=95/9=

10 5/9

4/3+10 5/9=12/9+10 5/9=11 8/9

Answer 2

Let's break down the expression step by step:

1. Start with the multiplication inside the parentheses: 5/4 * 3/1/5 To multiply fractions, multiply the numerators together and the denominators together: (5 * 3) / (4 * 1/5)

2. Simplify the multiplication: (15) / (4 * 1/5)

3. To multiply a fraction by a whole number, you can treat the whole number as a fraction with a denominator of 1: (15) / (4 * 1/5) = (15) / (4 * 5/1)

4. Now, multiply fractions by multiplying the numerators together and the denominators together: (15 * 1) / (4 * 5)

5. Simplify the multiplication: (15) / (20)

6. Reduce the fraction by dividing both the numerator and denominator by their greatest common divisor, which is 5: (15 / 5) / (20 / 5) = 3/4

Now, let's go back to the original expression:

4/3 + (3/4) / (9/10)

To divide fractions, you can multiply by the reciprocal of the second fraction:

4/3 + (3/4) * (10/9)

Now, multiply the fractions:

4/3 + (30/36)

Simplify the fraction:

4/3 + 5/6

To add these fractions, they need a common denominator, which is 6:

(4/3) * (2/2) + 5/6

Now, the fractions have a common denominator:

(8/6) + 5/6

Combine the fractions:

(8 + 5) / 6 = 13/6

So, the final result is 13/6.
