To solve this equation, we'll follow the order of operations (PEMDAS/BODMAS) which stands for Parentheses/Brackets, Exponents/Orders, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right).
Given equation:
[(¾) + (7/2)] / [5/4]
Step 1: Solve the fractions within the brackets
3/4 + 7/2
To add fractions, we need to find a common denominator. The least common multiple of 4 and 2 is 4.
3/4 + 7/2 = (3/4) + (7/2)(2/2) [Multiplying numerator and denominator of 7/2 by 2 to get a common denominator]
3/4 + 14/4 [Numerator multiplied by the same value, 2, to get a common denominator of 4]
Step 2: Combine like terms
3/4 + 14/4 = 17/4
So, the equation becomes:
17/4 / 5/4
Step 3: Divide the fractions
17/4 ÷ 5/4 = (17/4)(4/5) [Dividing by a fraction is the same as multiplying by its reciprocal]
17/4 * 4/5 = 17/5
So, the solution to the equation is 17/5.
