Answer 1

Ответ:

3 1/3

Пошаговое объяснение:

12 1/2 : 3 3/4 = 25/2 : 15/4 = 25/2 * 4/15 = 100/30 = 10/3 = 3 1/3

Answer 2

To find the full solution for the expression 12 1/2 : 3 3/4, we need to perform the division operation. First, let's convert the mixed numbers to improper fractions:

12 1/2 = (2 * 12 + 1) / 2 = 25/2 3 3/4 = (4 * 3 + 3) / 4 = 15/4

Now, we can rewrite the expression as:

(25/2) / (15/4)

To divide fractions, we multiply the first fraction by the reciprocal of the second fraction. The reciprocal of 15/4 is 4/15, so we have:

(25/2) * (4/15)

To multiply fractions, we multiply the numerators together and the denominators together:

(25 * 4) / (2 * 15) = 100/30

Now, we can simplify the fraction by dividing both the numerator and denominator by their greatest common divisor (GCD), which is 10:

100/30 = (100/10) / (30/10) = 10/3

Therefore, the full solution for 12 1/2 : 3 3/4 is 10/3.
