Question

(2•3/15+3•4/18)•16/15=

Answer 1

(2×3/15+3×4/18)×16/15=(6/15+4/6)×16/15=(6/15+2/3)×16/15=(6/15+10/15)×16/15=16/15×16/15=256/225=1 31/225

Answer 2

Let's simplify the expression step by step:

1. First, simplify the fractions inside the parentheses:

   2 * (3/15) + 3 * (4/18)

   To simplify these fractions, you can find common denominators:

   2 * (1/5) + 3 * (2/9)

2. Now, multiply each term by its respective number:

   (2/5) + (6/9)

3. To add these fractions, you need a common denominator, which is 45:

   (18/45) + (30/45)

4. Now, add the fractions:

   (18/45) + (30/45) = 48/45

5. Finally, multiply the result by 16/15:

   (48/45) * (16/15)

6. Simplify the multiplication:

   (16/15) * (48/45) = (16 * 48) / (15 * 45) = 768/675

So, (2•3/15+3•4/18)•16/15 simplifies to 768/675.
