Dean works with baby animals at a Zoo. This week he measured a giraffe, an ape and a tiger. The tiger had grown 4 inches less than the giraffe. The giraffe had grown twice as much as the ape. The baby ape had grown 6 inches since it was measured the last time.
How many inches had the tiger grown?
show your work and explain your answer.

This is not third grade.

deff. not 3rd grade.. but anyways..
say tiger= giraffe4inches
girafee= 2 x ape
ape= 6 inches
therefore,
giraffe= 2 x 6= 12 inches
therefore,
tiger= 12 inches  4 inches =8 inches 
The giraffe grew 12in. The tiger grew 8in.
