Question

Сократите в виде и запишите из в виде десятичных дробей 12 /15, 21/35, 12/30, 45/50, 18/90, 56/80, 9/12

Answer 1

12/15 = 4/5 = 0,8    (сокращение на 3)
21/35 = 3/5 = 0,6    (сокращение на 7)
12/30 = 4/10 = 0,4  (сокращение на 3)
45/50 = 9/10 = 0,9  (сокращение на 5)
18/90 = 1/5 = 0,2    (сокращение на 18)
56/80 = 7/10 = 0,7  ( сокращение на 8)
9/12 = 3/4 = 75/100 = 0,75   (сокращение на 3)

Answer 2

Simplifying Fractions

To simplify fractions, we need to find the greatest common divisor (GCD) of the numerator and denominator, and then divide both the numerator and denominator by the GCD.

Let's simplify the given fractions:

1. 12/15: - The GCD of 12 and 15 is 3. - Dividing both the numerator and denominator by 3, we get 4/5.

2. 21/35: - The GCD of 21 and 35 is 7. - Dividing both the numerator and denominator by 7, we get 3/5.

3. 12/30: - The GCD of 12 and 30 is 6. - Dividing both the numerator and denominator by 6, we get 2/5.

4. 45/50: - The GCD of 45 and 50 is 5. - Dividing both the numerator and denominator by 5, we get 9/10.

5. 18/90: - The GCD of 18 and 90 is 18. - Dividing both the numerator and denominator by 18, we get 1/5.

6. 56/80: - The GCD of 56 and 80 is 8. - Dividing both the numerator and denominator by 8, we get 7/10.

7. 9/12: - The GCD of 9 and 12 is 3. - Dividing both the numerator and denominator by 3, we get 3/4.

So, the simplified fractions are: - 12/15 = 4/5 - 21/35 = 3/5 - 12/30 = 2/5 - 45/50 = 9/10 - 18/90 = 1/5 - 56/80 = 7/10 - 9/12 = 3/4
