Question

what are the positive values of the remainder r when a positive integer a is divided by 3

Answer 1

Hello freind

let's make it it easy

let a be the divisor b the dividend and q be the some integer

by Euclid division algorithm we obtain

a = 3q+r where r = 0 or > 0 , 1 , 2

Hence possible value are for r - 0 , 1 ,2

Answer 2

let a be a positive integer

by Euclid division algorithm a=bq+r.

for some integer q>0 and r=0,1,2

because 0<r<b and here the B =3

so r=0,1,2
