Two shirts cost $12.50. How much will it cost to buy five of the shirts?
12.5 * 5 = ?
Select all the pairs of ratios that form a proportion. Which are:
1/6,4/20
7/9,28/36
14/18,21/27
30/80,6/18.
7/9,28/36
14/18,21/27
For which value of m is 4/16=m/24 a proportion
Cross multiply and solve for m.
16m = 96
m = 96 / 16
m = 6
t/16=40/50
Cross multiply and solve for t.
