Answer 2

To calculate the expression (33:30-4/5) × 2 + 2/9 + 2/5, let's break it down step by step:

First, we need to simplify the division (33:30) by finding the quotient.

33 divided by 30 is 1 with a remainder of 3. So the result of (33:30) is 1.

Next, we perform the multiplication (1 - 4/5) × 2:

1 - 4/5 is equivalent to (5/5 - 4/5) which gives us 1/5.

Now, we multiply 1/5 by 2:

1/5 × 2 is equal to 2/5.

Moving on to the addition part, we have 2/9 + 2/5:

To add these fractions, we need to find a common denominator. The least common multiple of 9 and 5 is 45.

Now, let's convert the fractions to have a denominator of 45:

2/9 can be converted to (2/9) × (5/5) = 10/45.

2/5 can be converted to (2/5) × (9/9) = 18/45.

Adding the fractions, we have:

10/45 + 18/45 = 28/45.

Finally, we add the result of the multiplication to the result of the addition:

2/5 + 28/45.

To add these fractions, we need a common denominator, which is 45:

2/5 can be converted to (2/5) × (9/9) = 18/45.

Now, we can add the fractions:

18/45 + 28/45 = 46/45.

So the final result is 46/45.
