Use the properties of operations and rules for multiplying and dividing to solve:
(9)÷(54)×(79)×(−5)÷(72)
To solve this expression, we can use the properties of division and multiplication.
First, let's start by multiplying the numbers:
(9) × (79) × (−5) = -3,555
Next, let's divide this result by 54:
-3,555 ÷ 54 = -65.83333333 (rounded to the nearest decimal place)
Lastly, let's divide this result by 72:
-65.83333333 ÷ 72 = -0.91319444 (rounded to the nearest decimal place)
Therefore, (9) ÷ (54) × (79) × (−5) ÷ (72) is approximately equal to -0.9132.
Hey bot your there ?
To solve the expression (9) ÷ (54) × (79) × (-5) ÷ (72), we will follow the order of operations and then simplify step by step.
1. First, perform the division operation:
9 ÷ 54 = 1/6
Now, our expression becomes:
(1/6) × (79) × (-5) ÷ (72)
2. Next, multiply the numbers together:
(1/6) × (79) × (-5) = -395/6
Now, our expression becomes:
(-395/6) ÷ (72)
3. Finally, divide the numbers:
(-395/6) ÷ (72) = -395/432
So, the simplified expression is -395/432.
To solve the expression (9)÷(54)×(79)×(−5)÷(72), we will use the properties of operations and rules for multiplying and dividing.
Step 1: Start by multiplying and dividing from left to right.
9 divided by 54 equals 1/6: (1/6)×(79)×(−5)÷(72)
Step 2: Multiply 1/6 by 79.
(1/6) times 79 equals 79/6: (79/6)×(−5)÷(72)
Step 3: Multiply (79/6) by -5.
(79/6) times -5 equals -395/6: (-395/6)÷(72)
Step 4: Divide (-395/6) by 72.
To divide fractions, multiply the first fraction by the reciprocal of the second fraction. Therefore, (-395/6) divided by 72 becomes (-395/6) times (1/72). Simplifying gives -395/432.
So, the simplified value of the expression (9)÷(54)×(79)×(−5)÷(72) is -395/432.
