What is 1.2 divided by 0.4?

Explanation:
Dividing decimals can be made easier by removing the decimals. Multiply both numbers by 10: 0.4 becomes 4 and 1.2 becomes 12. Now you’re really doing 12 divided by 4, which equals 3. This also fits the check that 0.4 times 3 equals 1.2, so it goes in exactly three times. Quick checks: 0.4 × 2 = 0.8, 0.4 × 2.5 = 1.0, 0.4 × 4 = 1.6—only 3 gives the exact 1.2.
