RATIOS AND PROPORTIONS Comparing two sets of items. Written with “to”, “:”, and as a “fraction”. *** Always remember to simplify into smallest terms *** ★★★★★¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢ For every 1 star there are 3 circles. 5:15 = 1:3
UNIT RATE “For each” “How Much is One” “Rate of” “Per” Set up a proportion – cross multiple or find the pattern $ Cost $ = $ Cost $ # of items 1 item
Time = Time # #
Fraction, Decimal, Percent
F % / 100
Divide
Rate in tables = Find the pattern
D
X 100
%
PERCENT OF QUANTITY % / 100
25% = 25/100 = .25
Ex. 30% = 30/100
VARIABLES EQUIVALENT EXPRESSIONS Combine Like Terms, Distribute 3 (2 + x) = 6 + 3x y + y + y = 3y
Represent an unknown number You can SOLVE for a variable by performing the opposite operation 10 + x = 15 15 – 10 = 5 x=5
