To solve this problem, we need to divide the number in the center (1690) by the numbers in the green ring. Then, we write down the
Quotient (Q) and the
Remainder (R) for each section.
Here is the step-by-step calculation for each part:
1. Top Left Section: Divide by 2
* Calculation: $1690 \div 2$
* Since 1690 is an even number, it divides perfectly.
* $1600 \div 2 = 800$
* $90 \div 2 = 45$
* $800 + 45 = 845$
*
Q = 845,
R = 0
2. Bottom Left Section: Divide by 10
* Calculation: $1690 \div 10$
* When dividing by 10, you just remove the zero at the end.
*
Q = 169,
R = 0
3. Bottom Right Section: Divide by 1000
* Calculation: $1690 \div 1000$
* 1000 goes into 1690 one time ($1 \times 1000 = 1000$).
* The remainder is what is left over: $1690 - 1000 = 690$.
*
Q = 1,
R = 690
4. Top Right Section: Divide by 100
* Calculation: $1690 \div 100$
* 100 goes into 1690 sixteen times ($16 \times 100 = 1600$).
* The remainder is what is left over: $1690 - 1600 = 90$.
*
Q = 16,
R = 90
Final Answer:
Top Left: Q = 845, R = 0
Bottom Left: Q = 169, R = 0
Bottom Right: Q = 1, R = 690
Top Right: Q = 16, R = 90
