Astudent ate 3/20 of all candies and another 1.2 lb. another student ate 3/5 of the candies and the remaining 0.3 lb. altogether, what weight of candies did they eat?

21/58.

hope to be marked brainliest

on monday rodney ate 1/4th of the sandwich = 3/12

on tuesday he ate 1/3rd of the sandwich = 4/12

therefore in total he has eaten = 3/12 + 4/12 = 7/12

thus we can say that he has eaten 7/12 of the sandwich on monday and tuesday alltogether.

happy to

pls mark as brainliest.
