Answer

\( 629 \div 4 = 157 \frac{1}{4} \)

Solution

To divide \( 629 \div 4 \) using the partial quotients method and express the remainder as a fraction, follow these steps: ### Step-by-Step Solution: 1. **Initial Division:** - **Find how many times 4 fits into 600:** \[ 4 \times 100 = 400 \] \[ 629 - 400 = 229 \] **Partial Quotient:** 100 2. **Next Division:** - **Find how many times 4 fits into 200:** \[ 4 \times 50 = 200 \] \[ 229 - 200 = 29 \] **Partial Quotient:** 50 3. **Subsequent Division:** - **Find how many times 4 fits into 20:** \[ 4 \times 5 = 20 \] \[ 29 - 20 = 9 \] **Partial Quotient:** 5 4. **Final Division:** - **Find how many times 4 fits into 8:** \[ 4 \times 2 = 8 \] \[ 9 - 8 = 1 \] **Partial Quotient:** 2 5. **Combine the Partial Quotients:** \[ 100 + 50 + 5 + 2 = 157 \] - **Remainder:** 1 6. **Express the Remainder as a Fraction:** \[ \text{Remainder} = \frac{1}{4} \] ### Final Answer: \[ 629 \div 4 = 157 \frac{1}{4} \]

The Deep Dive

To solve \( 629 \div 4 \) using partial quotients, we can start by estimating how many times 4 fits into 629. Let's say we take away multiples of 4 from 629: - First, we can subtract \( 4 \times 100 = 400 \) from 629. We get \( 629 - 400 = 229 \). So, count 100. - Next, we can subtract another \( 4 \times 50 = 200 \). Now we have \( 229 - 200 = 29 \). So, add 50 to our count: 100 + 50 = 150. - Now, let's see how many times 4 goes into 29. We can subtract \( 4 \times 7 = 28 \). Thus, \( 29 - 28 = 1 \). So, add 7 to our count: 150 + 7 = 157. Now we are left with 1, which is our remainder. To express the remainder as a fraction, we note that \( \frac{1}{4} \) is our remaining part when dividing by 4. So, \( 629 \div 4 = 157 \) with a remainder of \( \frac{1}{4} \).
