What is 9 over 5 times 5 over 9?
9/5 * 5/9 = 1, because 9*5 is 45 and 5*9 is 45, the problem becomes 45/45, which is 1. To multiply fractions: # Simplify the fractions if not in lowest terms. # Multiply the numerators of the fractions to get the new numerator. # Multiply the denominators of the fractions to get the new denominator. Simplify the resulting fraction if possible.
How do you simplify expressions with variables?
You multiply out brackets, remove common factors from fractions, combine like terms.
1 over 12 times 4 over 9?
Multiply the numerators of both fractions. That's the numerator of the result.Also, multiply the denominator of both fractions. That's the denominator of the result. Simplify as appropriate. Actually, it helps to simplify before doing the actual multiplication.
What is the state rule for dividing fractions?
Take the 2nd fraction, switch the denominator with the numerator, multiply across, simplify.
How do you multiply fractions with different denominators?
To multiply fractions, multiply the numerators together and the denominators together. For fractions a/b and c/d, the answer will be (a x c) / (b x d). Then simplify if possible. Numerical example : 2/5 x 3/8 = (2 x 3)/ (5 x 8) = 6/40 which equals 3/20
How do you you cross multiply?
if youre dealing with fractions then you multiply top by top and bottom by bottom then simplify
How you multiply fractions?
To multiply fractions, multiply the numerators by the numerators, and the denominators by the denominators, and then (if possible) simplify the resulting fraction. For example, 2/3 x 4/5 = 8/15
How do you subtract two fractions?
You have to find a common denominator, multiply them, subtract them and then simplify if you need to.
How do you multiply frations in math problems?
When you multiply fractions just line them up (denominator and denominator, numerator and numerator) then multiply across. Simplify.
How do you multiply and divide similar fraction?
To multiply two fractions, multiply the numerators together, then the denominators, then put the new numerator over the new denominator. Simplify if you can. To divide fractions, invert the second fraction and multiply as just described.
What is 9 over 5 times 5 over 9?
9/5 * 5/9 = 1, because 9*5 is 45 and 5*9 is 45, the problem becomes 45/45, which is 1. To multiply fractions: # Simplify the fractions if not in lowest terms. # Multiply the numerators of the fractions to get the new numerator. # Multiply the denominators of the fractions to get the new denominator. Simplify the resulting fraction if possible.
When you multiply fractions why do you multiply the fractions strait across?
This has the effect of producing a denominator in the answer that has each of the original denominators as factors. You don't have to worry about simplifying the fractions before multiplying. Of course, you may have to simplify after multiplying. There's no way out.
How do you simplify an algebraic expression that has fractions?
Multiply every term in the expression by the least common multiple of all the denominators. That will get rid of all fractions.
How do you simplify expressions with variables?
You multiply out brackets, remove common factors from fractions, combine like terms.
What are 3 steps you follow when multiplying fractions?
1. Multiply the numerators together. 2. Multiply the denominators together. 3. Simplify, if possible.
How do you divide mixed fractions by mixed fractions?
make each fraction a improper fraction the flip the second fraction and multiply straight across then simplify
