How do you find a fractional distance between two points, C and D?

Back

To find a fractional distance, multiply the total distance between C and D by the fraction (e.g., for 2/7, calculate (2/7) * distance CD).

Front

If point Q is 2/7 the distance from C to D, how do you express this mathematically?

Back

Q = C + (2/7) * (D - C).

Front

What is the significance of the numerator in a fraction?

Back

The numerator indicates how many parts of the whole are being considered.

Front

What is the significance of the denominator in a fraction?

Back
