you should use the ratio so

2/ 4 = 6.5 / n

n= 6.5 x 4 / 2 = 13 inches


2- for two hours ------> four inches of snow
for x hours -----> y inches of snow
the equation is
2/4 = x/ y

x= 2y / 4
for x is the hours and y is the inches

exercice 2
5 gr granula ----------------------> 1750 calories
2 gr granula ----------------------> n ?? calories

by cross multiplication
n = 2 x1750 / 5 = 700 calories .

2-
she wants to eat 175 calories so
u put granula under granula and calories under calories to make this cross

5 gr granula ----------------------> 1750 calories
??? m granula ---------------------> 175 calories
by cross multiplication
m = 175 x 5 / 1750 = 0.5 gr of granula
