how do u find
-9/20 X 120 - 6 X (-1/3)
-9/20 X 120 = -54
If you subtract 6 from that, you get -60
If you multiply that by -1/3, you get 20.
You need to learn how to use parentheses to clarify the order of operations.
-9/20 X 120 - 6 X (-1/3)
= (-9/20)(120) - 6(-1/3)
following BEDMAS we get
-54 + 2
= -52
To find the value of the expression -9/20 × 120 - 6 × (-1/3), you need to follow the order of operations, also known as the "BIDMAS" rule.
BIDMAS stands for:
1. Brackets (parentheses)
2. Indices (exponents and roots)
3. Division and Multiplication (from left to right)
4. Addition and Subtraction (from left to right)
Let's break down the expression step by step:
Step 1: Evaluate the multiplication within the expression.
-9/20 × 120 = -9/20 × (120/1) (Here, we can multiply the fractions directly, multiplying the numerators and the denominators.)
= (-9 × 120) / (20 × 1)
= -1080/20
= -54
Step 2: Deal with the negative sign.
Now we have -54 - 6 × (-1/3). When multiplying a number by a negative value, the sign flips. So, -6 × (-1/3) becomes 6 × (1/3) = 6/3 = 2.
Step 3: Perform the final subtraction.
-54 - 2 = -56
Therefore, -9/20 × 120 - 6 × (-1/3) evaluates to -56.
