The pie graph shows katie and david's household budget. the 25% mark represents utilities. if katie and david spend $400 a month on utilities, what is the total monthly budget?
a) $1200
b) $1600
c) $2000
d) $2500

Answer is B. $1,600

Given:
part = $400
percentage of the part = 25%
whole = ?

To get the whole or total monthly budget, simply divide the part by its corresponding percentage.

$400 / 0.25 = $1600

Other formulas to consider if other facts are given:

% of Part to the Whole = Part/Whole * 100%
                                     = 400/1600 * 100% 
                                     = 0.25 * 100%
                                     = 25%

Value of the part of a whole = Whole * % of part
                                              = 1600 * 25%/100% 
                                              = 400

128/3reason being 5 and 1/3 = 16/316/3 • 2/3 = 32/31 and 1/3 = 4/3 32/3 • 4/3 this will equal 128/3
