Use <em>CPCTC</em> and make ratios and proportionalities to find the value of segment PW:
If △WPJ∼△DNJ, then according to CPCTC, WP must be proportional to DN and PJ must be proportional to JN. Now, we can make a ratio:
Substitute the values that are given in the diagram.
DN=87.5
NJ=56
PJ=64
Solve for x. You can do it by cross-multiplication.
The measure of segment WP is 100 meters.

Answer:
0.7 gallons, 950 mL, 0.4 L, 1 1/4 cups
Step-by-step explanation:
First we need to convert the information given into one unit, in this case I will convert it into liters (L)
CUPS
1 cup is equal to 236.588 ml and is the same as .236 L using this information and knowing that 1 1/4 cup is the same as 1.25 cups we have that
x=.295 L
LITERS
0.4 L will stay the same
MILILITERS
1 liter is 1000 ml so 950 ml is the same as
x=.950 L
GALLONS
1 gallon is 3.78541 L so 0.7 gallons are
x=2.649 L
arranging the data from greatest to least we have that 0.7 gallons, 950 mL, 0.4 L, 1 1/4 cups
