cross-multiplying
No!If numerator and denominator have the same signs the fraction is positive.If numerator and denominator have opposite signs the fraction is negative.
Make sure that the numerator and denominator have different signs.
Yes, this is an example of direct variation.A:This is a direct variation because both are in the numerator of a fraction and on opposite sides of the = sign. If they are both on the same side of the equals sign, then one would have to be in the numerator and the other in the denominator for them to be a direct variation.
You don't. If you are dividing fractions, you multiply by the reciprocal. For example, 2/3 times 6/11 is 2/3 * 6/11 = 4/11. But, 2/3 divided by 6/11 is 2/3 * 11/6 = 11/9 or 1 2/9. The reason you do this is because the numerator is being multiplied and a denominator is being divided. When you divide, you are doing the opposite of multiplying so you flip the fraction, which is an opposite operation then you can multiply, which is the opposite of dividing.
When the numerator gets bigger, the fraction gets bigger; that is, it has a greater value The opposite is true if the denominator gets bigger; in this case the the fraction gets smaller; that is, it has a lesser value

Numerater is the correct answer
To put fractions into opposite fractions, all you have to do is flip it so that the numerator becomes the denominator and the denominator becomes the numerator. This is called a reciprocal. Example: The opposite of 3/5 is 5/3
Geographically if not mathematically. The numerator is the top number of a fraction and the denominator is the bottom number. They work together to tell how many parts out of the total number of parts are available.
Make sure that the numerator and denominator have different signs.

70/80 You can multiply the numerator and the denominator by the same number. Opposite of reducing a fraction.
Actually the reciprocal of any number is that number in the denominator instead of in the numerator. The reciprocal of -3 is 1 over -3.
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.
Since the hypotenuse (denominator) is always greater than the opposite or adjacent side (numerator), the ratio will always be smaller than one.
You don't. If you are dividing fractions, you multiply by the reciprocal. For example, 2/3 times 6/11 is 2/3 * 6/11 = 4/11. But, 2/3 divided by 6/11 is 2/3 * 11/6 = 11/9 or 1 2/9. The reason you do this is because the numerator is being multiplied and a denominator is being divided. When you divide, you are doing the opposite of multiplying so you flip the fraction, which is an opposite operation then you can multiply, which is the opposite of dividing.
Proper fractions have a numerator (top number) that is smaller than it's denominator (lower number). Improper fractions are the opposite, so 9/4 is improper.
