2. Answer:9/2 (or) 4.5

   Step-by-step explanation:Conversion of mixed fraction into improper fraction:

   A mixed fraction is in the form A b/c

   Step 1: Multiply the denominator by the whole number. c x A

   Step 2: Add the result to the numerator. (c x A) + b

   Step 3: The result in step 2 is the new numerator.

   Step 4: The denominator remains the same

   Step 5: Result = [(c x A) + b]/c

   15 1/2 = [(2 x 15) + 1]/2 = 31/2

   1 3/4 = [(4 x 1) + 3]/4 = 7/4

   The given equation can be simplified using BODMAS(Brackets of Division Multiplication Addition Subtraction)

   15 1/2 -[12/5× 5/8+(7÷1 3/4)]×2 = 31/2 – [12/5 x 5/8 + (7 ÷ 7/4)] x 2

   = 31/2 – [12/5 x 5/8 + (7 x 4/7)] x 2

   [Since, 7 ÷ 7/4 = 7 x 4/7]

   = 31/2 – [3/2 + 4] x 2

   [Since, 12/5 x 5/8 = 3/2 and 7 x 4/7 = 4]

   = 31/2 – [11/2] x 2

   [Since, 3/2 + 4 = 11/2]

   = 31/2 – 11

   [Since, [11/2] x 2 = 11]

   = (31 – 22)/2

   = 9/2
