Step-by-step explanation:

subtract 1. 3645/3= 1215

add 2 3648/3 = 1216

Answer:

i) 1

ii) -1

Step-by-step explanation:

i) on dividing 3646 by 3 the resulting remainder will be 1

on subtracting 1 from 3646 the number obtained will be 3645 which is divisible by 3

eg : 3646 - ( 1) = 3645

therefore ans is : 1

ii) on dividing 3646 by 3 the resulting remainder will be 1

here unlike the subtraction problem we have to change the sign of the remainder 1 to -1

after adding -1 to 3646 the answer obtained is 3645 which is divisible by 3

eg : 3646 + (-1) = 3645
