Answer 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
