If the sum of three consecutive numbers is 2022, what is their first number

first number: 673

second number: 674

third number: 675

Step-by-step explanation:

so, you add

x + x + 1 + x + 2 = 3x + 3.

3x + 3 = 2019

subtract 3 from both sides, to cancel out the opposite. you then get 2019. so then you divide 2019 by 3 to then get 673.

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.
