Often, the is beneficial to write the multiplication table the the divisor before you divide. | |||
Example 1. The division is by 16. Right here is the multiplication table of 16: 3 × 16 = 484 × 16 = 645 × 16 = 806 × 16 = 96 7 × 16 = 112 8 × 16 = 128 9 × 16 = 144 | | 0 3 | |
16 | ) | 5 5 6 8 |
16 goes into 5 zero times, so we look in ~ 55.
How many times does 16 go into 55?
Check in the table onthe left. We check out it walk into55 3 times.

Now, how many times walk 16 get in 76?
From the table we deserve to see that it is four times.

Lastly, 16 goes right into 128exactly 8 times, and also thedivision is over.
Example 2. us are splitting by 32. Here is the multiplicationtable of 32:
3 × 32 = 964 × 32 = 1285 × 32 = 1606 × 32 = 1927 × 32 = 2248 × 32 = 2569 × 32 = 288 -

Table that 14:2 × 14 = 3 × 14 = 4 × 14 = 5 × 14 = 6 × 14 = 7 × 14 = 8 × 14 = 9 × 14 = |
Table that 51:2 × 51 = 3 × 51 = 4 × 51 = 5 × 51 = 6 × 51 = 7 × 51 = 8 × 51 = 9 × 51 = |
4. Mental math! If 20 goes into 800 fourty times, then 20 goes right into 820 one time more, or 41 times. In each box, use the top difficulty to help you resolve the bottom problem.
a. 800 ÷ 20 = 820 ÷ 20 = | b. 700 ÷ 50 = 750 ÷ 50 = | c. 150 ÷ 15 = 300 ÷ 15 = |
d. 480 ÷ 40 = 520 ÷ 40 = | e. 600 ÷ 30 = 690 ÷ 30 = | f. 1,200 ÷ 60 = 1,320 ÷ 60 = |
b. convert 245 inches right into feet and inches.
