Access full lesson containing this video at: http://www.yourteacher.com/prealgebra/equivalentfractions.php Students learn that two fractions are equivalent if the fractions are the same when they are written in lowest terms. For example, 4/7 and 8/14 are equivalent fractions, because they are both equal to 4/7 when written in lowest terms. Students also learn to find fractions that are equivalent to a given fraction by multiplying the numerator and denominator of the given fraction by the same number. For example, to find fractions that are equivalent to 1/8, multiply the numerator and denominator by 2, to get 2/16, multiply the numerator and denominator by 3, to get 3/24, and so on.

Using the application pages from apple and i don’t mean a dash like this: 1/2. I want to know how to make fractions with numbers on top of each other

try character mapping

In math, factoring by grouping means that the greatest common factor needs to be found. Factor four different terms through grouping with help from a math author and teacher in this free video on math lessons.

I need to test myself on my fractions and I don’t know if my answers are correct. How do I do fractions on a calculator to find out?

Well, since fractions are equivalent to divisions, just substitute every fraction separator (as in 1/4) with a divisor (as in 1÷4).

A simple mistake during a mathematical calculation leads to devastating consequences.

I have a test coming next next week on fractions and I want to know how you add, subtract, multiply and divide fractions? I also want to know about LCD’s and those sorts of things. What if the denominator is not alike? What do I do? Thanks to all who tried.

Add and subtract:
First the fractions must have the same denominator. Then add or subtract their numerators.

Multiplication:
Multiply numerators by numerators, multiply denominators by denominators.

Division: (The number that is divided is called the dividend. The number that divides the dividend is called divisor.)
Invert the divisor and multiply the two fractions as described above.

Access full lesson containing this video at: http://www.yourteacher.com/prealgebra/multiplyfractions.php Students learn to multiply fractions by multiplying across the numerators, and multiplying across the denominators. For example, to multiply 1/2 x 3/7, multiply across the numerators, 1 x 3 = 3, and multiply across the denominators, 2 x 7 = 14. So 1/2 x 3/7 = 3/14. Students also learn to cross-cancel when multiplying fractions. For example, to multiply 3/5 x 5/9, the 3 and 9 cross-cancel to 1 and 3, and the 5 and 5 cross-cancel to 1 and 1. Therefore, 3/5 x 5/9 can be rewritten as 1/1 x 1/3, and multiplying across the numerators and denominators, 1/1 x 1/3 = 1/3.

What if there were 1 or 2 negatives, and you had to order them from least to greatest.

Would you order the highest negative number first as the least, then the lowest negatives, then all the positives?

and One last question, whats the fastest way to order percents, fractions and decimals?

by looking at how much, or what? I need to be able to do this tomorrow, and I only have 5 minutes for 48 fractions percents and decimals.

you should convert all to the same form, that is, all fractions (hardest), or all decimals (easiest) or all percents (dopiest).

Then put them on a number line. Of course, more to the left is less than a number to the right.

Negatives go to the left, the bigger the absolute value, the more to the left.

Hope this helps.
