1. 2 3/5+ 3 4/5 Rewrite the mixed numbers as fractions;
= 13/5 + 19/5 Write the sum of the numerators over the common denominator;
= (13 + 19)/5
= 32/5 Rewrite the fraction as a mixed number;
= 6 2/5
2. -2 1/5 + (- 4 5/8) Rewrite the mixed numbers as fractions;
= -11/5 + (-37/8) Multiply by 8/8 the first fraction, and by 5/5 the second fraction in order to have the same denominator (because LCD is 40);
= -88/40 + (-185/40) Write the sum of the numerators over the common denominator;
= -(88 + 185)/40
= -273/40 Rewrite the fraction as a mixed number;
= -6 33/40

Steps for multipling fractions and mixed numbers?
to multiply fractions add them together and reduce the final fraction. to multiply mixed numbers, first make the mixed number an improper fraction, by mulitplying the whole number and the denominator and adding the answer to the numerator. Example: The improper fraction 8/5 can be changed to the mixed number 1 3/5 by dividing the numerator (8) by the denominator (5). This gives a quotient of 1 and a remainder of 3. The remainder is placed over the divisor (5).
When adding two mixed numbers if the sum of the fractions is greater than 1 you have to carry the 1 over to the whole number side?
That is correct.
How is adding like fractions and adding unlike fractions the same?
If the denominators are not the same, then you have to use equivalent fractions which do have a common denominator . To do this, you need to find the least common multiple (LCM) of the two denominators. To add fractions with unlike denominators, rename the fractions with a common denominator. Then add and simplify.
What are adding fractions?
adding fractions r easy math prblems. like 1/4 +1/4 = 1/2.
How do you solve all fractions problems?
You basically have to learn separately how to do different things with fractions, including finding a common denominator; converting fractions to a different denominator; simplifying fractions; adding and subtracting fractions; multiplying fractions; dividing fractions.
