How do you divide fractions with common denomonators?
switch numbers and multiply you should know that
When doing fractions why is it easier to multiply and divide fractions than add and substract fractions?
It is easier to multiply or divide fractions than to add or subtract fractions because in multiplication, you just have to multiply the numerator by the numerator and the denominator by the denominator. Same applies with division of fractions, except that you have to reciprocate the fraction you're dividing with (divisor) then proceed to multiplication. Whereas, in addition and subtraction of fractions, you still have to get their Least Common Denominator (LCD).
What math process uses reciprocals?
When you divide fractions you need to multiply by the reciprocal of the divisor. You would also use it anytime the multiplicative inverse is required.
Why do you invert fractions?
When you divide by fractions, you invert and multiply.
How do you multiply a percent by a percent?
Multly the two numbers the percents are and then divide them by 10,000. Divide them by 10,000 because this the 100x100, the two bottom fractions, and being a fraction you divide
What does it mean to multiply and divide fractions?
multiply and divide fractions!-.-
How do 4th graders divide and multiply fractions?
The same way anyone else does. To multiply fractions, multiply the top numbers together and then the bottom numbers together. The two totals become the top and bottom number, respectively, of the new fraction. To divide fractions, flip the second fraction upside down and multiply it.

How do you multiply and divide mixed numbers?
First convert them into improper fractions. And then to multiply multiply both the numerators and the denominators. To divide just take the reciprocal ofthe denomiator anjd then multiply them.
What is the numbers you divide by?
The divisor.

When you divide fractions you need to multiply by the reciprocal of the divisor. You would also use it anytime the multiplicative inverse is required.
Do you need a common denominator to divide fractions?
No. Dividing fractions is achieved by inverting the divisor and multiplying the resulting fractions. To multiply fractions the numerators are multiplied together to form the new numerator and the denominators are multiplied together to form the new denominator.
Why do you invert fractions?
When you divide by fractions, you invert and multiply.

What fraction is between 1.2 and 1.205?
To find a fraction between any two numbers, multiply the two numbers and divide by two. This way we can find unlimited numbers / fractions between any two fractions/numbers. The other way to find fractions between any two fractions is to divide and multiply both the numbers by 100, or 1000, and make the denominators same. Then the numbers between the two numerators gives all the numbers/fractions between those two numbers. For example, to find 100 fractions between 1 and 2, multiply and divide 1 and 2 by 100. This gives 100/100 and 200/100. Now the in between fractions are 101/100, 102/100, 103/100 upto 199/100. To find more, either multiply by 1000 instead of 100 to get 999 fractions. Or use any two numbers above and repeat the same process. To find fractions between 1.2 and 1.205, multiply and divide both numbers by 10000 This gives 12000/10000, 12050/10000. So the in between fractions are 12001/10000, 12002/10000 and so on till 12049/10000. Convert them to decimal.
What is the difference between cross and across?
When you add or subtract fractions you cross multiply and when you multiply or divide fractions you across multiply.
