Let’s solve each decimal division problem step by step. We’ll go one at a time, and I’ll show you how to think about them so it makes sense.
---
1) 0.28 ÷ 0.7
Think: How many times does 0.7 fit into 0.28?
We can make this easier by multiplying both numbers by 10 to get rid of the decimal in the divisor:
→ 0.28 × 10 = 2.8
→ 0.7 × 10 = 7
Now we have:
2.8 ÷ 7
7 goes into 2.8 exactly 0.4 times (because 7 × 0.4 = 2.8)
✔ Answer:
0.4
---
2) 0.021 ÷ 0.03
Multiply both by 100 to eliminate decimals:
→ 0.021 × 100 = 2.1
→ 0.03 × 100 = 3
Now:
2.1 ÷ 3 = 0.7
✔ Answer:
0.7
---
3) 0.054 ÷ 0.9
Multiply both by 10:
→ 0.054 × 10 = 0.54
→ 0.9 × 10 = 9
Now:
0.54 ÷ 9 = 0.06
(Because 9 × 0.06 = 0.54)
✔ Answer:
0.06
