John wanted to divide
25 pieces of gum among his 6 friends. If he gave each friend 4 pieces, he would use
24 pieces.
6 friends X 4 pieces = 24 pieces of candy.
John has 25 pieces of candy. He would have 1 piece of candy left.
25 pieces - 24 pieces = 1 piece of candy.
John has a remainder of 1 piece of candy.
25 -:- 6 = 4 remainder 1.
Look at the next example.
17 -:- 5 = ___ or 17 -:- 5 = 3 remainder 2.
3 X 5 = 15 and 15 is 2 away from 17. Thus 17 -:- 5 = 3
r 2.
We use r to shorten the word remainder.
Complete the following.
9 -:- 4 =
remainder 1
13 -:- 4 = 3 remainder
23 -:- 7 = 3 remainder
11 -:- 3 =
remainder 2
28 -:- 5 = 5 remainder
47 -:- 7 =
remainder 5
55 -:- 9 = 6 r
65 -:- 7 =
r 2
Complete the following.
19 -:- 5 = 3 r
21 -:- 5 =
r 1
33 -:- 6 = 5 r
50 -:- 7 =
r 1
19 -:- 5 =
r 4
31 -:- 7 = 4 r
43 -:- 9 =
r
27 -:- 4 =
r
77 -:- 8 =
r
57 -:- 6 =
r
41 -:- 6 =
