be good people (: brainliest A keem measured the capacity of a glass as 2 7 0 mL and the capacity of a Th e rm o s® a s 1 L. He said that the ratio 270 :1 compare s the capacity of the glass with the cap a c i t y of the Th e rm o s®. Is his reasoning corre c t ? E x p l a i n .

Step-by-step explanation:

i'm not sure i quite understand, could you provide more information?
