How do you subtract improper fractions with whole numbers?
To subtract an improper fraction from a whole number, turn the whole number into a fraction with the same denominator as the improper fraction. Then minus. All whole numbers actually have a "1" as a denominator, we just don't write it (it's assumed.) E.g 10 = (10/1) 20 = (20/1) etc... to change the denominator to the same as the improper fraction, multiply the whole number (that is now a fraction over "1") by the denominator of the improper fraction. E.g Let the improper fraction be 17/4, and your real number be 20. From above, we know that 20 is the same as "20/1", with "1" as the denominator. You want this "1" to be "4", so multiply the real number by "4/4" (which is essentially multiplying by 1, so doesn't mess up how big the fraction is) 20/1 x 4/4 = 80/4. Now the denominators of both fractions are the same, you can minus the improper fraction from the whole number. i.e 80/4 - 17/4 = 63/4 Which is actually 15 3/4 .
How do you turn two and two ninths to an improper fraction?
To convert a mixed number to an improper fraction, multiply the denominator by the whole number, add that total to the numerator and put the whole thing over the original denominator. 20/9
How do you turn mixed numbers into improper fractions?
Divide the numerator by the denominator. The largest integer quotient is the whole number , the remainder is the numerator , and you use the same denominator. Examples 15/7 = 2 plus remainder 1 = 2 1/7 32/30 = 1 plus remainder 2 = 1 2/30 = 1 1/15
How do you do mixed numbers?
turn them into improper fractions
How do you turn improper fractions to mixed numbers?
You multiply the denominator by the whole number and then you add the top half of the fraction to that number. You put the number you get over the original denominator and that is your answer.actually,you divide the numerator to the denominator or the other way around
