Determine the value of the expression -5.45 + 4.12 - 8.66.
-5.45 + 4.12 - 8.66 = -9.54
To determine the value of the expression -5.45 + 4.12 - 8.66, you need to perform the arithmetic operations in order from left to right.
Here's the step-by-step process:
1. Start with the first operation: -5.45 + 4.12.
Add -5.45 and 4.12 together. The sum is -1.33.
2. Now, work with the second operation: -1.33 - 8.66.
Subtract 8.66 from -1.33. The result is -10.99.
Therefore, the value of the expression -5.45 + 4.12 - 8.66 is -10.99.
Determine the value of the expression -5.45 + 4.12 -8.66.
The value of the expression -5.45 + 4.12 - 8.66 is equal to -9.99.
Evaluate this expression. 32 + (-72.1)
The value of the expression 32 + (-72.1) is equal to -40.1.
Consider this expression: 1/4 - 0.5 + 1/2 - 0.25 + 3/5 + 0.4. You are asked o find the sum of the expression by using fractions. Which expression could you use? (No mixed fractions)
To find the sum of the expression 1/4 - 0.5 + 1/2 - 0.25 + 3/5 + 0.4 using fractions, we can convert the decimal numbers to fractions with a common denominator and then add the fractions together.
The expression can be rewritten as:
1/4 - 2/4 + 2/4 - 1/4 + 3/5 + 2/5
Now, we can add the fractions together:
(1/4 - 2/4) + (2/4 - 1/4) + (3/5 + 2/5)
Simplifying each pair of fractions within parentheses:
-1/4 + 1/4 + 5/5
The denominators in each pair of fractions have already been converted to a common denominator, so we can directly add the numerators:
(1 - 2 + 2 - 1 + 3 + 2) / 4
Simplifying the numerator:
6 / 4
Finally, we can reduce the fraction:
3 / 2
Therefore, the sum of the expression 1/4 - 0.5 + 1/2 - 0.25 + 3/5 + 0.4 using fractions is 3/2.
