What is the mathematical term the product of the mean equals the product of the extremes?
: The product of the means is equal to the product of the extremes. When you cross multiply to show 2 fractions are equivalent. Ex a/c =b/d so cross multiplying would show a x d = c x b c x b are the means a x d are the extremes Their products are equal in a proportion or equivalent fractions that is the answer and it is correct
What is the cross product method?
If a is to b as c is to d, a x d = b x c. The product of the means (b & c) equals the product of the extremes (a & d).
Why does cross multiplying with fractions work?
When cross multiplying, finding the product of the means and extremes, you are technically getting a common denominator that reduces out.
How do you write a proportion?
One standard way is it use colons , For example 7:14::6:12 read as 7 is to 14 as 6 is to 12. The number in the middle are called the means; those on either end are called the extremes. In a correct proportion, the product of the means equals the product of the extremes. In the example, note that 7 times 12 = 14 times 6.
How many inches are in 3 over 4 of a yard?
one yard is 36 inches, so 1/4 of a yard is 36/4=9. So 3/4 of a yard would be 9x3, or 27 inches A common method of solving problems like this is through the principle that for equal fractions, the product of the means is equal to the product of the extremes. 3 over 4 is equal to what over 36. Using the variable "x" for what, this can be written as 3/4 = x/36. The product of the means (4 & x) is equal to the product of the extremes ( 3 & 36), or 4x= 3 times 36 4x= 108 so divide both sides of the equation by 4, gives us x=27
