Question

2 3\5 p + 2 2\3 при р = 5

Answer 1

2 3/5 · 5 + 2 2/3 = 13 + 2 2/3 = 15 2/3

Answer 2

To solve the expression, let's first convert the mixed numbers into improper fractions.

2 3/5 can be written as (2 * 5 + 3) / 5 = 13/5. 2 2/3 can be written as (2 * 3 + 2) / 3 = 8/3.

Now we can substitute p with 5 and calculate the expression:

13/5 * 5 + 8/3

To add fractions with different denominators, we need to find a common denominator. In this case, the least common multiple (LCM) of 5 and 3 is 15.

(13/5 * 5/1) + (8/3 * 5/5) = (65/5) + (40/15)

Now that the fractions have the same denominator, we can add them:

(65 + 40) / 15 = 105/15

The fraction 105/15 can be simplified by dividing both the numerator and denominator by their greatest common divisor, which is 15:

105/15 = (7 * 15) / (1 * 15) = 7/1 = 7.

Therefore, when p = 5, the expression 2 3/5 p + 2 2/3 equals 7.
