Measures, Money And Accuracy
Bayani Gaba-gaba
A recipe scaled from four servings to eleven, a currency converted for a holiday budget, a bridge span measured to the nearest centimetre: every real measurement or amount of money needs a consistent set of units and an honest statement of how precise it really is.
This topic ties together unit conversions, money calculations, the four ways of writing the same proportion (fraction, decimal, percentage, ratio), rounding to a given accuracy, the upper and lower bounds that a rounded measurement could hide, and standard form for very large or very small numbers.
