Circle the numbers you've multiplied
You can find a missing denominator if you know something that the fraction is equal to. Then you can find the missing denominator through cross multiplication.
The answer depends on what other information you have.
The answer depends on what other information you have.
To find a missing numerator or denominator in a fraction, you can set up a proportion using the known values. For example, if you have the fraction 2/x = 3/6, you can cross multiply to find the missing numerator: 26 = 3x. Solve for x to find the missing denominator. Alternatively, if you have the fraction y/4 = 5/10, you can cross multiply to find the missing numerator: y10 = 54, and then solve for y to find the missing numerator.
An equivalent fraction is just a multiple of the one that you have (i.e it is the one that you have, scaled up or down). So multiply the fraction that you have until either the numerator or the denominator match the given numerator/denominator of the fraction with the missing number. The number in the corresponding place on the fraction that you multiplied is the missing number.
If you have a missing numerator (top number), divide the new denominator (bottom number) by the original denominator and multiply this by the numerator.If you have a missing denominator, divide the new numerator by the original numerator and multiply this by the denominator.examples:1/2 = ?/6Dividing denominators: 6 ÷ 2 = 3 Multiplying the numerator: 1 x 3 = 3⇒ 1/2 = 3/61/4 = 3/?Dividing numerators: 3 ÷ 1 = 3 Multiplying the denominator: 4 x 3 = 12⇒ 1/4 = 3/126/8 = ?/4Dividing denominators: 4 ÷ 8 = 1/2 Multiplying the numerator: 6 x 1/2 = 3⇒ 6/8 = 3/43/6 = 2/?Dividing numerators: 2 ÷ 3 = 2/3 Multiplying the denominator: 6 x 2/3 = 4⇒ 3/6 = 2/4
Restate question: In working with equivalent fractions, how do you find a missing numerator?(If this is not your question, please resubmit your question with more information.)Example: Find an equivalent fraction for 2/5, with a denominator of 30.Solution: 2/5 = x/30. Since 30 = 5x6, you need to multiply the numerator by 6. 2x6=12.2/5 = 12/30.
Divide the product by the factor[s] you know. The answer is the missing factor.
The answer depends on the numbers that ARE available.
The answer depends on the part of the question that is missing.
6/8=6/8
That really depends on what information is given.
