Determine each sum or difference. Write all fraction answers as mixed numbers. Place a space between the whole number and the fraction. Use the slash key, /, to separate the numerator and denominator. For example, the number four and one half would be entered as 4 1/2.
-2 2/3+4 1/5= I think it's 4
3 13/15?
Negative 4- Positive 2
-4 + 2 Is it 1 then?
Nope.
To determine the sum of -2 2/3 and 4 1/5, you need to add the whole numbers, fractions, and simplify the fraction if needed. Here's how to solve it step by step:
1. Add the whole numbers: -2 + 4 = 2.
2. Add the fractions: 2/3 + 1/5 = To add fractions with different denominators, you need to find a common denominator. In this case, the common denominator is 15.
- Multiply the numerator and denominator of 2/3 by 5 to get 10/15.
- Multiply the numerator and denominator of 1/5 by 3 to get 3/15.
Now you can add the fractions: 10/15 + 3/15 = 13/15.
3. Simplify the fraction: The fraction 13/15 cannot be simplified further, so it remains as 13/15.
4. Combine the whole number and fraction: The final answer is 2 13/15.
Therefore, the sum of -2 2/3 and 4 1/5 is 2 13/15, not 4.
-2 2/3+4 1/5
-2 10/15 + 4 3/15 = ?
It's not 4.
