Math worksheet for practicing division by multiples of positive powers of ten.

Let’s solve each division problem step by step. Remember: dividing by a multiple of 10 (like 10, 100, 1000) is easy — you just move the decimal point to the left based on how many zeros are in the divisor.

For example:
- Dividing by 10 → move decimal 1 place left
- Dividing by 100 → move decimal 2 places left
- Dividing by 1000 → move decimal 3 places left
- And so on!

We’ll go row by row.

Wait — looking back at the original image layout, it seems there are two columns with 25 problems each? But actually, counting again — let me recheck the structure.

Actually, from the image description, it looks like there are 5 rows per column and 5 columns? Wait no — let me recount properly.

Looking at the user's text version:

It shows:

Left side:
30÷5, 30÷50, 10÷500, 35÷5000, 30÷50000
Then 16÷8, 16÷80, 16÷800, 16÷8000, 16÷80000
Then 90÷9, 90÷90, 90÷900, 90÷9000, 90÷90000
Then 15÷5, 15÷50, 15÷500, 15÷5000, 15÷50000
Then 8÷2, 8÷20, 8÷200, 8÷2000, 8÷20000

Right side:
14÷7, 14÷70, 14÷700, 14÷7000, 14÷70000
Then 10÷2, 10÷20, 10÷200, 10÷2000, 10÷20000
Then 24÷2, 24÷20, 24÷200, 24÷2000, 24÷20000
Then 3÷1, 3÷10, 3÷100, 3÷1000, 3÷10000
Then 10÷2, 10÷20, 10÷200, 10÷2000, 10÷20000 ← this last group repeats the earlier one? That might be a typo in the image or transcription.

But since we’re solving what’s given, I’ll assume all 50 problems are to be solved as listed.

However, notice that “10 ÷ 2” etc. appear twice — once in the middle right and once at the bottom right. We’ll solve them both as written.

So total answers:

Let me list them in order as they appear in the image (left to right, top to bottom):

Row 1:
30÷5 = 6
14÷7 = 2
30÷50 = 0.6
14÷70 = 0.2
10÷500 = 0.02
14÷700 = 0.02
35÷5000 = 0.007
14÷7000 = 0.002
30÷50000 = 0.0006
14÷70000 = 0.0002

Row 2:
16÷8 = 2
10÷2 = 5
16÷80 = 0.2
10÷20 = 0.5
16÷800 = 0.02
10÷200 = 0.05
16÷8000 = 0.002
10÷2000 = 0.005
16÷80000 = 0.0002
10÷20000 = 0.0005

Row 3:
90÷9 = 10
24÷2 = 12
90÷90 = 1
24÷20 = 1.2
90÷900 = 0.1
24÷200 = 0.12
90÷9000 = 0.01
24÷2000 = 0.012
90÷90000 = 0.001
24÷20000 = 0.0012

Row 4:
15÷5 = 3
3÷1 = 3
15÷50 = 0.3
3÷10 = 0.3
15÷500 = 0.03
3÷100 = 0.03
15÷5000 = 0.003
3÷1000 = 0.003
15÷50000 = 0.0003
3÷10000 = 0.0003

Row 5:
8÷2 = 4
10÷2 = 5
8÷20 = 0.4
10÷20 = 0.5
8÷200 = 0.04
10÷200 = 0.05
8÷2000 = 0.004
10÷2000 = 0.005
8÷20000 = 0.0004
10÷20000 = 0.0005

All calculations verified.
