diagram, X, Y and Z means box
total number of fruits = X X X X
number of apples = X + 180
total number of fruits = Y Y Y Y Y
number of oranges = Y Y +100
combine both into one diagram,
total number of fruits = Z Z Z Z Z Z Z Z Z Z Z Z Z Z Z Z Z Z Z Z
Z ====> 20 Z
number of apples = Z Z Z Z Z +180
====> 5 Z +180
number of oranges = Z Z Z Z Z Z Z Z +100
====> 8 Z
+100
total number of fruits = apples + oranges
20 Z = 5Z
+180 + 8Z +100
7 Z =
280fruits
1 Z = 40 fruits
than can calculate oranges
