The temperature on a winter night was -23 f. the temperature rose by 5 f when the sun came up . when the sun set again , the temperature dropped by 7 f . write and evaluate an expression to find the temperature after the sun set .

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.
