2/5:5/6=2ц6+2=2ц2/6

1/2×2/5=2/5-1/1=2/5

Answer 2

To solve the expression, let's break it down step by step:

Step 1: Add 3/5 and 5/6. To add fractions, find a common denominator, which in this case is 30. (3/5)(6/6) + (5/6)(5/5) = 18/30 + 25/30 = (18 + 25)/30 = 43/30

Step 2: Add 43/30 to 2 (2 whole). To add a whole number to a fraction, convert the whole number to a fraction with the same denominator. 2 = 2/1 43/30 + 2/1 = (43 + 60)/30 = 103/30

Step 3: Subtract 1/2 from 2/5. To subtract fractions, find a common denominator, which in this case is 10. (2/5)(2/2) - (1/2)(5/5) = 4/10 - 5/10 = (4 - 5)/10 = -1/10

Step 4: Divide 1 by 1 1/9. To divide fractions, convert the whole number to a fraction and then invert the second fraction and multiply. 1 1/9 = (9 + 1)/9 = 10/9 1 ÷ 10/9 = 1 * 9/10 = 9/10

Step 5: Subtract 9/10 from 103/30. To subtract fractions, find a common denominator, which in this case is 30. (103/30)(10/10) - (9/10)(3/3) = 1030/300 - 27/30 = (1030 - 27)/300 = 1003/300

Now, we can simplify the final fraction:

Step 6: Simplify 1003/300 by finding the greatest common divisor (GCD) and dividing both numerator and denominator by it. GCD of 1003 and 300 is 1.

1003 ÷ 1 = 1003 300 ÷ 1 = 300

So, the simplified result is 1003/300.

Please note that if you need the result as a mixed number or a decimal, you can further simplify the fraction accordingly.
