On 1 February 2007, Math Reading Group at SCC watched a Discovery Channel video clip about fractions. The video clip used a fraction having five as the numerator and eight as the denominator.

5 --- 8The fraction was used to demonstrate the problem of an ancient tribe having to equally share five loaves of bread between eight people.

let 'B' be a loaf of bread and 'P' is a person B B B B B P P P P P P P P not every 'P' can have a 'B' divide each 'B' into two equal halves forming ten 'b' each 'b' is 1/2 of a 'B' b b b b b b b b b b P P P P P P P P each 'P' gets one 'b' with two 'b' leftover b b P P P P P P P P divide each 'b' into 4 equally sized pieces forming 8 'e' each 'e' is 1/8 of a 'B' e e e e e e e e P P P P P P P P each 'P' gets one 'e' with zero 'e' leftover therefore, each 'P' gets 1/2 + 1/8 of a 'B'Fractions must have a common denominator when added together.

`1/2`

and`4/8`

areequivalentfractions because`1 divided-by 2`

equals`4 divided-by 8`

Decimal numbers (i.e. numbers with decimal points; floating-point; real) and percents. Each 'P' received 5/8 of 'B'. The fraction can be morphed into a decimal number and a percentage.

5 / 8 = 0.625 0.625 x 100% = 62.5% each 'P' got to eat 62.5% of all the 'B'
