Question

91/4*8-12/3*51/2-24/5*211/12

Answer 1

$\frac{91}{4}$ * 8 - 4 * $\frac{51}{2}$ - $\frac{24}{5}$ * $\frac{211}{12}$ = -4,4

1) $\frac{91*8}{4}$ = 182

2) $\frac{4*51}{2}$ = 102

3) $\frac{24*211}{5*12}$ = $\frac{422}{5}$ = 84,4

4) 182 - 102 = 80

5) 80 - 84,4 = -4,4

Answer 2

To solve the expression, follow the order of operations (PEMDAS/BODMAS):

P - Parentheses (or Brackets) E - Exponents (or Orders, Indices) MD - Multiplication and Division (from left to right) AS - Addition and Subtraction (from left to right)

Let's apply these rules step by step:

1. Perform the multiplications and divisions from left to right:

91/4 * 8 = 182/1 = 182 12/3 * 51/2 = 4 * 51/2 = 102 24/5 * 211/12 = 48.4 (rounded to one decimal place)

2. Now, rewrite the expression with the calculated values:

182 - 102 - 48.4

3. Perform the subtractions:

182 - 102 = 80 80 - 48.4 ≈ 31.6

So, the result of the expression 91/4 * 8 - 12/3 * 51/2 - 24/5 * 211/12 is approximately 31.6.
