The distance between two points is the number of units between them.

<u>Halfway points (a) and (b)</u>

To locate a point halfway points (a) and (b), we use the following steps

  • Calculate the absolute difference between both points
  • Divide the absolute difference by 2
  • Add the quotient to the smaller point.

Assume the smaller value is (a), the point (P) halfway points (a) and (b) would be

P = a + \frac{|a - b|}{2}

Take for instance, a = 5, and b = 10.

The halfway point would be:

P = 5 + \frac{|5 - 10|}{2}

P = 5 + \frac{5}{2}

P = 5 + 2.5

P = 7.5

The halfway point between 5 and 10 is 7.5

The formula works for negative values, and absolute values are used to return the actual difference between both points

<u>Real world circumstance</u>

The formula can be used to calculate the halfway distance between a school gate and the school library (as an instance)

<u>Fractional distance</u>

To determine the fractional distance, we simply replace the 1/2 in the original formula with the appropriate fraction.

Take for instance, three-fourths from (a) to (b) would be:

P = a + \frac{3|a - b|}{4}

Carmela mixes 3/4 kilogram of walnuts, 1/2 kilogram of almonds, and 1/4 kilogram of pecans together. She divides the mixed nuts
Evgesh-ka [11]

Amount of walnuts=\frac{3}{4} kg

Amount of almonds=\frac{1}{2} kg

Amount of pecans=\frac{1}{4} kg

Total amount=\frac{3}{4}+\frac{1}{2}+\frac{1}{4}

LCM is 4 so sum is = \frac{3+2+1}{4}=\frac{6}{4} =\frac{3}{2}

As given, Carmela divides the mixed nuts into 3/10 kilogram bags so number of bags will be:

\frac{\frac{3}{2}}{\frac{3}{10}}

= \frac{3}{2}\times\frac{10}{3} = 5

Hence, answer is 5 bags.
