Step-by-step solution for: Division of Decimals by 2-digit number - Math Worksheets
To solve the problems involving division of decimals, we need to follow these steps:
1. Adjust the divisor to a whole number: Move the decimal point in the divisor to the right until it becomes a whole number. Move the decimal point in the dividend the same number of places to the right.
2. Perform the division: Divide the adjusted numbers as you would with whole numbers.
3. Place the decimal point in the quotient: The decimal point in the quotient will be directly above the decimal point in the dividend.
Let's solve each problem step by step.
---
- Adjust the divisor: Move the decimal point 2 places to the right in both the divisor and the dividend.
- Divisor: \( 0.58 \rightarrow 58 \)
- Dividend: \( 0.5568 \rightarrow 55.68 \)
- Perform the division: \( 55.68 \div 58 \)
- \( 58 \) goes into \( 556 \) (first two digits of \( 55.68 \)) approximately \( 9 \) times.
- \( 58 \times 9 = 522 \)
- Subtract: \( 556 - 522 = 34 \)
- Bring down the next digit: \( 348 \)
- \( 58 \) goes into \( 348 \) approximately \( 6 \) times.
- \( 58 \times 6 = 348 \)
- Subtract: \( 348 - 348 = 0 \)
- Quotient: \( 0.96 \)
Answer: \( 0.96 \)
