Division and Multiplication – Inverse Operations
Look at these examples:
12 x 13 = 156
13 x 12 = 156
156 &divide; 12 = 13
156 &divide; 13 = 13
Can you see a pattern? Multiplication and division are inverse
operations; this means they are the opposites of each other. By
knowing the answer to one of the above problems you can work
out all the others.
Work out the other problems in each of these groups, in your book.
The first has been started for you.
1)6 x7 = 42
7x6=?
42 &divide; ? = 7
?&divide;7=6
2) 5 x 6
3) 8 x 7
4) 11 x 4
5) 8 x 9
6) 6 x 4
7) 8 x 4
8) 7 x 9
Use the inverse operations to complete the following:
9) 16 x 11 = 176
11 x 16 = ?
176 &divide; 11 = ?
176 &divide; 16= ?
10) 14 x 15 = 210
15 x 14 = ?
210 &divide; 14 = ?
210 &divide; 15 = ?
11)204&divide;12=17
204&divide;17=?
17 x 12 = ?
12 x 17 = ?
Use your table knowledge to solve the following mentally:
12) 56 &divide; 7
13) 42 &divide; 7
14) 81 &divide; 9
15) 24 &divide; 6
