Answer 2

Sure! Let's break down the expression step by step:

1. First, we need to simplify the expression inside the parentheses:

   6 - 4 8/15 = 6 - (4 + 8/15)

   To add 4 and 8/15, we need to find a common denominator. The easiest way is to convert 4 to an improper fraction:

   6 - (4 + 8/15) = 6 - (60/15 + 8/15)

   Now we can add the two fractions:

   6 - (60/15 + 8/15) = 6 - 68/15

   To subtract fractions, we need a common denominator, which is already 15. So we can simply subtract the numerators:

   6 - 68/15 = (90/15) - (68/15) = 22/15

2. Now we can divide 22/15 by 2.2. To divide a fraction by a decimal, we can convert the decimal to a fraction by putting it over 1 and then multiplying the two fractions:

   22/15 ÷ 2.2 = 22/15 × 1/2.2

   To multiply fractions, we multiply the numerators and denominators separately:

   22/15 × 1/2.2 = (22 × 1) / (15 × 2.2)

   Multiplying the denominators, we get:

   (22 × 1) / (15 × 2.2) = 22 / 33

   So the final answer is 22/33 or simplifying it, 2/3.
