Challenge: Order the Steps to Convert Gallons to Cups
To convert from gallons to cups, you can follow these ordered steps:
-
Find cups (c) that equals 1 gallon (gal). The unit ratio.
(1 gallon = 16 cups) -
Set up the proportion.
(If 1 gallon = 16 cups, then 850 gallons = x cups) -
Cross multiply and solve for x.
(Cross-multiplication will give you x = 850 * 16)
So the correct order is: 1, 2, 3.
Question 5: Find x when 1 cm = x inches
Given the conversion factor:
- \( 1 , \text{inch} = 2.54 , \text{cm} \)
You can find \( x \) in two ways:
-
Algebraically:
Rearrange the equation to isolate \( x \).
\[ 1 , \text{inch} = 2.54 , \text{cm} \implies 1 , \text{cm} = \frac{1}{2.54} , \text{inches} \] -
Using ratios:
Set up a ratio based on the known conversions:
\[ \frac{1 , \text{cm}}{x , \text{inches}} = \frac{1 , \text{inch}}{2.54 , \text{cm}} \]
These two methods allow you to solve for x.
