To solve this problem you must apply the proccedure shown below:

 1. You have the following information given in the problem above:

 - <span>The length of a rectangle is 7 1/2 inches and its width is 4 3/4 inches

 2. Therefore, the ratio is:

 7 1/2 inches=7.5 inches=15/2=30/4
 4 3/4 inches= 4.75 inches=19/4

 length:width
 30:19

 The answer is the option b: B. 30:19

Ratio is a division in its simplest form. 
To get the ratio of length to width, divide the two then simplify.

In this case, convert the length and width into decimals.

length = 7 1/2 = 7.5
width 4 3/4 = 4.75

ratio of length to width is;
7.5/4.75 = 750/475

This can now be written as; 
750 : 475
Dividing both sides by 25;

= 750/25: 475/25

= 30 : 19

A group of 485 people take a canoe trip. They fill up all avalible canoes that each hold 3 people with 273 people. The rest of t
Jobisdone [24]
Answer:
3c=273
c=91
2c= 212
C= 106
c= 91+ 106= 197
so they will need 197 canoes total

Why:
So first you have to determine a set variable to represent the number of canoes, I chose C. Then you make an equation to represent the number of canoes 273 people will use if they group into 3's, from this I got 3c=273. Solve for C and get 91.
The remainder of the group which is 485-273= 212 will use canoes in groups of 2's. To represent this, 2c=212. Solve for C and get 106. Combine 106 and 91 to get the total number of canoes.

BigorU [14]
Volume units quarts to gallons (fluid and dry) conversion factor is 0.25 (quart is 1/4 of an gallon). To find out how many gallons in quarts, multiply by the factor, or simply use the converter below. 1 Quart = 0.25 (1/4) Gallon [US, UK, Fluid or Dry] Quart and gallon are imperial and US customary volume measurement units. In US customary system, both units have different volume capacity for dry and fluid measurements but in imperial (UK), the volume is the same for both fluid and dry measurement.
