A robe takes 2 bolts of blue fiber and half that much white fiber. How many bolts in total does it take?
assistant
How many bolts of white fiber does it take? ** It takes 2/2=<<2/2=1>>1 bolt of white fiber
How many bolts in total does it take? ** So the total amount of fabric is 2+1=<<2+1=3>>3 bolts of fabric
