3/40 and 5/24
you have to multiply numerators and denominators because whatever you do to the bottom you have to do to the top
Yes because the numerators add up to equal a whole number which is 1
first you get the denominators the same then you multiply the number you multiplied to the denominator to the numerator then you add the two numerators together and keep the denominators the same then if needed you simplify
3/40 and 5/24
You need common denominators. Then add or subtract the numerators. If the answer is an improper fraction it is common practice to reduce it to a mixed number.
Yes. Fractions whose numerators and denominators are integers are rational numbers. Being negative does not change it into an irrational number.
First, unmix the numbers ((denominator times whole number plus numerator) over denominator). Then multiply the numerators together and the denominators together. The numerator of the product is the product of the numerators of all of the multiplicands, and the denominator of the product is the product of the denominators of all of the multiplicands. Third, simplify.
10/3 written as a mixed number in simplest form is 3 1/3 (you can check this answer) 3+(1/3) get common denominators (9/3)+(1/3) add the numerators 10/3 It is: 10/3 = 3 and 1/3
Numerators and denominators are just numbers; I hope you're not asking us to factor every number. There are many different methods. I prefer to find the prime factorization; that leads to all the other factors. Some people like to use a factor tree to help visualize the prime factorization.
-- Find a common denominator. (It will be a number of which all three denominators are factors. The best choice is their least common multiple.) -- Change the fractions to their equivalents with the common denominator. -- Then add their numerators to get the numerator of their sum.
You must find a common denominator. You figure out the smallest number that all of your denominators are divisible by. If you have to multiply the denominators by 2, you must multiply the numerators by 2, then add the numerators together, and write above the common denominator. If you have to multiply one denominator to equal the other denominator, then you must multiply the numerator above that denominator, and finally add up the numerators and place above the common denominator. Then reduce the answer to its smallest fraction.
