Steps to solve the problem:
Therefore, the solution to the problem is .
Solve the following exercise:
Multiplying both the dividend and divisor by the same number keeps the division result unchanged! It's like having - the ratio stays the same.
Look at the divisor and count decimal places. Since 0.2 has 1 decimal place, multiply both numbers by 10. If it were 0.02, you'd use 100.
That's normal! In our example, 1.49 × 10 = 14.9. You can still divide 14.9 ÷ 2 easily using long division or by recognizing 14.9 = 149 ÷ 10.
Yes! Moving the decimal point right is the same as multiplying by 10. Move both decimal points the same number of places to the right.
When you divide 14.9 ÷ 2, you get exactly 7.45, not 7. The .45 part matters - it represents 45 hundredths, which is significant in the final answer.
