the number is abc,def,ghi
d=5 so abc,5ef,ghi
f=d+3, so abc,5e8,ghi
a=f/2=4, so 4bc,5e8,ghi
b=a+d=9, so 49c,5e8,ghi
rest=0, so 490,508,000
write the roman numerals that comes before;
1. CDX__________
2. MMD____________
find the value of the missing number;
1. 48+85-N-39=21
2.96+15-N+76=100
To find the number, we'll need to analyze the given information step by step.
1. The digit in the hundred thousands place is 5.
- This means the number contains a 5 in the hundred thousands place.
2. The digit in the thousands place is 3 more than the digit in the hundred thousands place.
- We know from step 1 that the digit in the hundred thousands place is 5.
- Therefore, the digit in the thousands place is 5 + 3 = 8.
3. The digit in the hundred millions place is half the digit in the thousands place.
- We found in step 2 that the digit in the thousands place is 8.
- Therefore, the digit in the hundred millions place is 8 / 2 = 4.
4. The digit in the ten millions place is the sum of the digits in the hundred millions and hundred thousands places.
- From step 1, we know the digit in the hundred thousands place is 5.
- From step 3, we know the digit in the hundred millions place is 4.
- Therefore, the digit in the ten millions place is 5 + 4 = 9.
5. The rest of the digits are zeros.
- Given that only the hundred thousands, thousands, hundred millions, and ten millions places have specific digits, the remaining places are all zero.
Therefore, the number is: 90,048,500.
