Add fractions and decimals practice. What is negative one and 1/3+-4 2/3.
To add fractions, we need to have a common denominator. In this case, the common denominator is 3.
Therefore:
-1 and 1/3 + (-4 and 2/3)
To add the whole numbers, we have: -1 + (-4) = -5
Next, let's add the fractions: 1/3 + 2/3 = 3/3 = 1
Putting the whole number and fraction together, we have:
-5 1/3.
To add the fractions and decimals, -1 1/3 and -4 2/3, follow these steps:
1. Convert the mixed numbers to improper fractions:
-1 1/3 becomes -4/3
-4 2/3 becomes -14/3
2. Find a common denominator for the fractions, which is 3:
-4/3 remains the same
-14/3 remains the same
3. Add the fractions together:
-4/3 + (-14/3) = -4/3 - 14/3
4. Combine the numerators and keep the denominator the same:
-4 - 14 = -18
-18/3
5. Simplify the fraction if possible:
-18/3 can be simplified by dividing both the numerator and denominator by 3:
-18 ÷ 3 / 3 ÷ 3 = -6/1 = -6
Therefore, -1 1/3 + -4 2/3 = -6.
