What is the sum or difference in the simplest form 5 over 12 plus 1 over 3

1.  The ratio is 6:14 or 6/14,  3:7 or 3/7.

2. 2/8 or 1 out of 4.

4. At approximately  16c

a cup, Folgers Coffee is better value than Seattle's Best which costs  18c a cup.

Step-by-step explanation:

1. Talley, ratios work like fractions. The ratio is 6:14 or 6/14, which reduces to 3:7 or 3/7.

2. If 8 out of 10 prefer Crest, then 2 out of 10 do not.  The ratio of those who  do not prefer Crest (2) to those that do prefer Crest (8) is 2/8 or 1 out of 4.

4. To find the respective value per cup, divide the prices give by the number of cups they represent. We shall represent Folgers Coffee by  f and Seattle's Best by  s

.

f = 12.88/80

= 0.161

Folgers Coffee is approximately  16

c per cup.

s = 9.00/50

s = 0.18
