Answer 2

Let's break down this expression step by step:

1. First, simplify each part of the expression:

   • 4 - 4 = 0
   • 15 + 1 = 16
   • 7/15 + 7/60 = (28/60) + (7/60) = 35/60 = 7/12
   • 3 2/3 = 11/3
   • 3 1/8 = 25/8
   • 2.75 = 11/4
   • 0.2 = 1/5
   • 2 1/8 = 17/8

2. Now, simplify the expression further:

   • (0 + 16 + 7/12) / (11/3) : ((25/8 - 11/4) / (1/5 * 17/8))

3. Continue simplifying:

   • (16 + 7/12) / (11/3) : ((25/8 - 11/4) / (1/5 * 17/8))

4. Find a common denominator for fractions in the numerators:

   • (192/12 + 7/12) / (11/3) : ((25/8 - 22/8) / (1/5 * 17/8))

5. Add fractions in the first numerator:

   • (199/12) / (11/3) : ((3/8) / (85/8))

6. Invert the second fraction and multiply:

   • (199/12) / (11/3) * (8/85)

7. Divide the fractions:

   • (199/12) * (3/11) * (8/85)

Now, multiply the numerators and denominators: Numerator = 199 * 3 * 8 = 4776 Denominator = 12 * 11 * 85 = 11220

So, the simplified result of the given expression is: 4776/11220

You can further simplify this fraction by dividing both the numerator and denominator by their greatest common divisor, which is 12: (4776/12) / (11220/12) = 398/935
