Question

4*1/3+4*2/5+4*2/15 помогите решить

Answer 1

4*1/3+4*2/5+4*2/15 = 4 *(1/3 + 2/5 + 2/15) = 4*(5/15 + 6/15 + 2/15) = 4 * 13/15 = 52/15 = 3 7/15

Answer 2

Sure, let's solve the expression step by step:

1. First, let's calculate 4 * 1/3: 4 * 1/3 = 4/3

2. Next, let's calculate 4 * 2/5: 4 * 2/5 = 8/5

3. Lastly, let's calculate 4 * 2/15: 4 * 2/15 = 8/15

Now, we add all the results together:

4/3 + 8/5 + 8/15

To add these fractions, they need to have the same denominator. The common denominator for 3, 5, and 15 is 15. So, let's convert all the fractions to have a denominator of 15:

(4/3) * (5/5) = 20/15 (8/5) * (3/3) = 24/15 (8/15)

Now, the expression becomes:

20/15 + 24/15 + 8/15

Add the numerators:

20 + 24 + 8 = 52

So, the final result is:

52/15

However, we can simplify this fraction:

52/15 = 3 and 7/15

Therefore, the result of the expression is 3 and 7/15.
