Math Problem Statement

Point X is at 2/3 on a number line. On the same number line, point Y is the same distance from 0 as point X, but it has a numerator of 8. What is the denominator of the fraction at point Y? Draw a number line to model the problem.

Solution

Let's solve this step by step:

Problem Analysis:

  1. Point XX is at 23\frac{2}{3} on the number line.
  2. Point YY is at the same distance from 0 as Point XX, but its fraction has a numerator of 8.
  3. We need to find the denominator of the fraction for Point YY.

Solution:

Step 1: Determine the distance of XX from 0

The distance of XX from 0 is given by the fraction 23\frac{2}{3}.

Step 2: Represent YY's distance with its fraction

Point YY is the same distance from 0 as Point XX. Let the fraction at YY be 8d\frac{8}{d}, where dd is the denominator we need to find. Since the distances of XX and YY from 0 are equal: 23=8d\frac{2}{3} = \frac{8}{d}

Step 3: Solve for dd

To solve 23=8d\frac{2}{3} = \frac{8}{d}, use cross-multiplication: 2d=382 \cdot d = 3 \cdot 8 2d=242d = 24 d=12d = 12


Final Answer:

The denominator of the fraction at YY is 12.


Number Line:

A simple number line can be drawn with points labeled for 00, 23\frac{2}{3}, and 812\frac{8}{12} (which is equivalent to 23\frac{2}{3}).
