How is adding mixed numbers different from adding fractions?
when you add mixed numbers you have a whole number but adding fraction does not.
How do you subtract mixed numbers with regrouping?
you take away one of the whole number=then you add or subtract your fractions=
How would you add or subtract fractions with like denominators?
The same way you would add or subtract whole numbers, leaving the denominators alone.
When adding mixed numbers should you add the whole numbers first or the fractions?
I personally would convert them to improper fractions, add them and then convert the result back to a mixed number. However, if you want to add the parts separately, it would be better to add the fractions first as this could result in a carry of a whole number to add into the addition of the whole numbers. eg 2 1/3 + 3 5/6 Adding fractions and whole numbers separately: Fractions: 1/3 + 5/6 = 2/6 + 5/6 = 7/6 = 1 + 1/6 = 1/6 + (carry to the whole numbers) Whole numbers: 2 + 3 + (carry) = 2 + 3 + 1 = 6 → 2 1/3 + 3 5/6 = 6 1/6 Done as improper fractions: 2 1/3 + 3 5/6 = (2x3+1)/3 + (3x6+5)/6 = 7/3 + 23/6 = 14/6 + 23/6 = 37/6 = (6x6+1)/6 = 6 1/6
How do you write mixed numbers in to improper fractions?
Multiply the denominator by the whole number, add that total to the numerator and put the whole thing over the original denominator.
