Answer 2

To simplify the expression 46/50:(7/20 - 11/15) + 3 * 11/15, follow the order of operations (PEMDAS/BODMAS):

1. First, perform the subtraction inside the parentheses:

   7/20 - 11/15 = (21/60) - (44/60) = (21 - 44)/60 = -23/60

2. Next, multiply 46/50 by the result from step 1:

   (46/50) * (-23/60) = (-23/25) * (-23/60)

3. Finally, add 3 * 11/15 to the result from step 2:

   (-23/25) * (-23/60) + 3 * 11/15

To add fractions, find a common denominator, which in this case is 60:

(-23/25) * (-23/60) = (23 * 23)/(25 * 60) = 529/1500

Now add 3 * 11/15:

3 * 11/15 = 33/15

Now, combine the two results:

529/1500 + 33/15

To add these fractions, we need a common denominator, which is 1500:

(529/1500) + (33/15) = (529/1500) + (220/1500)

Now that they have the same denominator, add the numerators:

(529 + 220)/1500 = 749/1500

To simplify the fraction, find the greatest common divisor (GCD) of 749 and 1500, which is 1:

(749/1) / (1500/1) = 749/1500

So, the simplified result of the expression is 749/1500.
