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
How do you subtract whole numbers by fractions?
Simplify them.
How do you add multiple mixed fractions?
Find a common denominator, add the numerators, simplify if possible.
How do you you cross multiply?
if youre dealing with fractions then you multiply top by top and bottom by bottom then simplify
When you multiply fractions why do you multiply the fractions strait across?
This has the effect of producing a denominator in the answer that has each of the original denominators as factors. You don't have to worry about simplifying the fractions before multiplying. Of course, you may have to simplify after multiplying. There's no way out.
How do you cross simplify?
Cross-simplification is a technique used to simplify the multiplication of fractions. It is possible when the fractions have common factors that can be divided out. For example the multiplication of the fractions 6/2 * 2/5 = (6*2)/(2*5). The 2's can be simplified out so that the multiplication is simply 6/1 * 1/5 = 6/5.
What is a step for multiplying fractions?
First line them up. Its jsut like normal multiplication. Mulitply them across as they are. Simplify the answer when done.
What is distributive property of multiplication?
The distributive property of multiplication lets you simplify expressions wherein you multiply a number by a sum or difference. According to this property, the product of a sum or difference of a number is equal to the sum or difference of the products.
How do you do cross multiplication?
Take the two fractions and put them side to side and multiply the numerator and the numerator and the denominator by the denominator and simplify if needed
1 over 12 times 4 over 9?
Multiply the numerators of both fractions. That's the numerator of the result.Also, multiply the denominator of both fractions. That's the denominator of the result. Simplify as appropriate. Actually, it helps to simplify before doing the actual multiplication.
Does the Identity Property of Multiplication work for Division?
NO it si like addition and subtraction IT DOESN'T WORK. Since Multiplication is somehow Addition made easier (4x2=8 ; 4+4=8), it can't be because Division is more of Subtraction and somehow to simplify answers at some cases. 1 x a = aa / 1 = a
How do you multyplt fractions?
You multiply the numerators of both fractions, and place the result in the numerator of the result. Similarly, the denominator of the result is the product of the denominators of the individual fractions. For example: 2/3 x 3/7 = (2x3) / (3x7) = 6/21 You can simplify the result in the usual way. However, it is usually simpler to simplify before doing the actual multiplication. In the above example, you can cancel (eliminate) the 3 in the numerator with the 3 in the denominator before doing the actual multiplication.
How are common factors useful?
They are useful in reducing fractions and to simplify radicals. They are useful in reducing fractions and to simplify radicals.
