5).
Define the units of proportion
1in/2ft = 5.25in/xft now cross multiply
1*x = 2*5.25
x = 10.5ft
Answer d
6).
Use this proportion
355,000ppl/54.9mi = x ppl/1 mi
54.9*x = 355,000*1 divide by 54.9
x = 6466.3
Answer b
11).
4pounds/0.89dollars = 7pounds/ x dollars
4x = 7*0.89
x=1.5575
Answer b
12).
5.5%/100 = x / 350
100x = 5.5%*$350
x = $19.25 interest
The total is $19.25+$350=$369.25
