Question

3 1/5 · a + a если а = 10

Answer 1

Ответ:

42

Пошаговое объяснение:

3 1/5 * a + a при а = 10

3 1/5 * 10 + 10 = 16/5 * 10 + 10 = 32 + 10 = 42

Answer 2

To evaluate the expression 3 1/5 · a + a, where a = 10, we can substitute the value of a into the expression and perform the calculations.

First, let's simplify the mixed number 3 1/5. To convert it to an improper fraction, we multiply the whole number (3) by the denominator (5) and add the numerator (1). Then we put the result over the denominator.

3 1/5 = (3 * 5 + 1)/5 = 16/5

Now we can substitute the value of a = 10 into the expression:

3 1/5 · a + a = (16/5) · 10 + 10

Next, we simplify the multiplication:

(16/5) · 10 = (16 · 10)/5 = 160/5 = 32

Finally, we can simplify the addition:

32 + 10 = 42

Therefore, when a = 10, the expression 3 1/5 · a + a equals 42.
