How would you add parenthesis and brackets to make this sentence true: 45/2•4.7-4.4•6=54

Sagot :

[45/(2 * 4.7) - (4.4)] * 6 = 54

Step 1: PEMDAS (Parenthesis first) 
2 × 4.7 = 9.4

Step 2: Still within the parenthesis: 9.4 - 4.4 = 5

Step 3: Finish within the parenthesis: 45 ÷ 5 = 9

Step 4: Last part of the equation: 9 × 6 = 54

Correct placement of brackets and parenthesis to make the statement true is:

[45/(2x4.7)-(4.4)]x6 = 54
