What is - 1 1/3 + - 4 2/3? I need help.
To add these mixed numbers, you can start by converting the mixed numbers to improper fractions.
- 1 1/3 = - 4/3
- 4 2/3 = - 14/3
Now, you can add the fractions:
- 4/3 + (- 14/3) = - (4/3 + 14/3)
To add the fractions, the denominators must be the same. In this case, both denominators are 3, so you can add the numerators:
- 4/3 + 14/3 = 10/3
Therefore, - 1 1/3 + - 4 2/3 = - 10/3.
What is - 1 1/3 + - 4 2/3 as a reduced mixed number.
To simplify the sum of - 1 1/3 and - 4 2/3 as a reduced mixed number, you can follow these steps:
1. Convert the mixed numbers to improper fractions:
- 1 1/3 = - (3/3 + 1/3) = - 4/3
- 4 2/3 = - (3/3 * 4 + 2/3) = - 14/3
2. Add the fractions:
- 4/3 + (- 14/3) = - (4 + 14)/3 = - 18/3 = - 6
3. Express the result as a mixed number:
- 6 can be written as - 5 1/3.
Therefore, - 1 1/3 + - 4 2/3 as a reduced mixed number is - 5 1/3.
What is -3 1/6 + 5 3/4 as a reduced mixed number?
To simplify the sum of -3 1/6 and 5 3/4 as a reduced mixed number, you can follow these steps:
1. Convert the mixed numbers to improper fractions:
-3 1/6 = - (6/6 * 3 + 1/6) = -19/6
5 3/4 = (4/4 * 5 + 3/4) = 23/4
2. Add the fractions:
-19/6 + 23/4
To add the fractions, the denominators must be the same. You can find a common denominator by multiplying the two denominators: 6 * 4 = 24.
3. Rewrite the fractions with the common denominator:
-19/6 * 4/4 = -76/24
23/4 * 6/6 = 138/24
4. Add the fractions:
-76/24 + 138/24 = 62/24
5. Express the result as a mixed number:
To simplify the fraction, you can divide the numerator and denominator by their greatest common divisor (GCD), which is 2 in this case:
62/24 ÷ 2/2 = 31/12
The mixed number can be found by dividing the numerator (31) by the denominator (12). The quotient becomes the whole number, and the remainder becomes the numerator of the fraction part:
31 ÷ 12 = 2 remainder 7
Therefore, -3 1/6 + 5 3/4 as a reduced mixed number is 2 7/12.
What is 13.92 + ( -22.111)?
