Flip the fraction around (the one after the division sign) and change it to a multiplication sign. (swap the numerator with the denominator) so 2/(3/10) = 2*(10/3)

The reason you do so is if you think of multiplication and dividing revolving around the number 1, in multiplying if you are above 1 then you are increasing if you are lower you are increasing. The opposite is the same of division. Effectively, if you think about it multiplication is the inverse of division and the other way around as well, so by flipping the fraction you are inverting it, so instead of dividing by 0.5 you multiply by 2. I hope this makes sense, it could be shown algebraically, but it is probably easier to understand this way.

Tell you how to divid fractions?

When you divide fractions you want to change it to a multiplication problem. You do this by changing the second fraction to its receptorial and change the division sign to a multiplication sign. Here is an example: 8/10 divided by 3/5 *first switch it to multiplication 8/10 times 5/3 *solve 40/30 *simplify 40/30=4/3 or 1 1/3


Why is multiplying or dividing the numerator and denominator by the same nonzero number the same as multiplying or dividing the fraction by 1?

because of mathematical equivalence: it doesn't change the result


How do you change 9.4 into a mixed number?

Any number divided by one or multiplied by one remains unchanged (identity properties of multiplication & division) so 9.4 = 9.4/1 Mulitply by 10/10 (which is 1 - so the value of your number does not change) = 94/10 = 9 4/10 = 9 2/5


Why does the sign change when multiplying and dividing negative numbers?

It changes because two negatives make a positive!!!!!!!!!!!!


Does the order in which you perform operations in a numerical expression matter?

Yes, unless all of the operations are additions, or all of them are multiplication. Otherwise, changing the order will change the result. The order of operations is determined by parentheses, or if none are present, by the PEDMAS sequence.The order in which mathematical operations must be done has the acronym PEDMAS or PEMDAS. PEDMAS or PEMDAS, no matter how you spell it, gives the correct order for mathematical operations: 1. P - Parentheses, 2. E - Exponents, MD - Multiplication and Division, AS - Addition and Subtraction.

Why do you change mixed numbers to improper fractions before multiplying and dividing?

Because common denominators allow adding and subtracting of numerators. Improper fractions also have simplified rules over mixed numbers when performing multiplication and division.


Does it matter what way the fractions are when your dividing?

Yes, you must flip them. for example, if you had 3/4 divided by 6/7, you would have to change the division sign to a multiplication sign. Then, you flip the second fraction. In this case, 7/6.

What happens when you divide a fraction by one?

when ever you divide fractions you must always flip the fraction you are dividing and change the division sign to multiplication, ex. 1/2 divded by 1 = 2/1 multiplied by 1/1 which equals 2


Do you change signs when dividing fractions?

Yes


Does the inequality sign change when both sides are multipled or divided when using fractions Why or why not?

Not if the fraction is positive. But yes if the fraction is negative. Study the rules of multiplication and division by integers, and you wil see why. Multiplication by a fraction is simplty multiplication by one integer followed by division by another (or the other way round).
