Question

15*(1 цел +1/3 )-1/5

Answer 1

15 * (1 + 1/3) - 1/5 = 15 4/5
1) 1 + 1/3 = 1 1/3
2) 15 * 1 1/3 = 15 * 4/3 = 15 : 3 * 4 = 16
3) 16 - 1/5 = 15 5/5 - 1/5 = 15 4/5

Answer 2

Let's break down the expression step by step:

1. 1 цел: It seems like "1 цел" is a typo or an incorrect representation. I assume you meant "1 целая" which translates to "1 whole" or simply 1.

2. 1/3: This is one-third.

3. 15*(1 цел + 1/3): We add 1 whole and one-third, which gives us 1 + 1/3 = 4/3.

4. 15*(1 цел + 1/3) - 1/5: Now, we subtract 1/5 from the previous result.

Let's calculate it:

15 * (4/3) - 1/5

To simplify this expression, we first find the common denominator, which is 15.

(15 * 4/3) - (1/5)

Now, let's perform the multiplication:

(60/3) - (1/5)

Next, we convert 60/3 to 20:

20 - (1/5)

Now, we have the same denominator, so we can subtract:

(20 * 5 - 1) / 5

(100 - 1) / 5

99/5

The final result is 99/5 or 19.8 in decimal form.
