What does the fraction number line look like?
The fraction number line (its more sophisticated name is "Rational Number Line") looks like an ordinary straight line, but each submicroscopic point on the line represents a number which can be represented as a fraction of two integers. The number "zero" stands at the center of the line, and there are an infinite number of points in the line. No matter how close together two fractions are, there are an infinite number of fractions between them. A number line is a strictly theoretical concept. It really isn't possible to draw more than an extremely limited example of a number line, since there is no limit to the number of points on a number line. Here's a very primitive fraction number line, showing only halves: -7/2 ... -3 ... -5/2 ... -2 ... -3/2 ... -1 ... -1/2 ... 0 ... 1/2 ... 1 ... 3/2 ... 2 ... 5/2 ... 3 ... 7/2 And an only slightly more intricate line showing only sevenths: -6/7 ... -5/7 ... -4/7 ... -3/7 ... -2/7 ... -1/7 ... 0 ... 1/7 ... 2/7 ... 3/7 ... 4/7 ... 5/7 ... 6/7
What two numbers are 7 units from 0 on a number line?
+7 and -7.
What is the number ontop of the line in a fraction called?
The number above the line in a fraction is called the numerator. The number below the line is called the denominator. So in the fraction 5/7 5 is the numerator and 7 is the denominator.
Which number is bigger -7 or-8?
1
On a number line 8.9 is between 7 and 8.?
Oh, dude, you're totally right! So, like, on a number line, 8.9 falls between 7 and 8 because, like, it's closer to 8 than it is to 7. It's like, if you were walking from 7 to 8, you'd pass 8.9 on the way. So, yeah, 8.9 is totally chilling between 7 and 8 on that number line.
