How do you divide negative fractions from positive fractions?
You divide the equivalent positive numbers. Then you add a negative sign to the result.
What happens when you divide a fraction by itself?
you change all mixed numbers to improper fractions.
Name three fractions whose decimal equivalent is 0.40?
The three fractions whose decimal equivalent is 0.40 are 4/10. 8/20 and 16/40. There are many more fractions that would have the same decimal result.
What are the steps to subtracting fractions?
Same as for addition. Mainly, you have to convert the fractions to equivalent fractions that have the same denominator. After that, it is easy: just subtract the numerators and put the result on top of the common denominator.
How did scientists find pi?
By dividing the diameter of any circle into its circumference will always result as pi.
What is always the result of dividing an integer when the divisor is nonzero?
A rational number is always the result of dividing an integer when the divisor is nonzero.
How do you arrange fractions in asending order?
Various methods: * Convert the fractions into equivalent fractions with the same denominator; then order by smallest numerator to largest; * Convert the fractions to [approximate] decimals by dividing the numerators by the denominators; then order by the smallest decimal to largest; * Divide the denominators by the numerators; then order by the largest result to the smallest. In all cases list the original fractions.
What are three fractions that are equivalent to 0.60?
1. Write this as 60/100. 2. Simplify the fraction as much as you can. 3. In the result of step (2), multiply top and bottom by the same number, to get an additional fractions. You can repeat (with the result of step (2)), multiplying top and bottom with different numbers (but always the same number for top and bottom), to get additional equivalent fractions.
How is dividing fractions different from multiplying fractions?
(3/4) x (5/9) = (3x5)/(4x9) = 15/36, that is when you multiply fractions, you multiply the numerators and form the numerator of the result and multiply the denominators and form the denominator of the result (3/4) / (5/9) = (3/4) x (9/5) = 27/20, that is when you divide fractions, you first invert the fraction by which you are dividing and then multiply the numerators and form the numerator of the result and multiply the denominators and form the denominator of the result

How do you add and subtract by fractions?
If the fractions have the same denominator, add and subtract the numerators as if the denominators weren't there and put the result over that denominator. Reduce if possible. If the fractions have different denominators, find the LCM of the denominators and convert the fractions to equivalent fractions with like denominators. Then add and subtract the numerators as if the denominators weren't there and put the result over that denominator. Reduce if possible.
Do you have to change the denominators when multiplying fractions?
No. To multiple fractions multiple the numerators together and multiply the denominators together and simplify (by dividing both numerator and denominator of the result by common factors until the only common factor is 1). The denominators only need to be the same when adding or subtracting fractions.
Why is multiplying mixed numbers less than dividing mixed numbers with fractions?
It depends on the numbers. For example, dividing by 1 1/2 (one and a half) is exactly the same as dividing by 3/2, since both represent the same number.In general, if you divide by a larger number, the result will be less.
