How many times does the digit 7 occur in the sequence of numbers from 1 to 763 (inclusive)?

To find the number of times 7 occurs from 1 to 763, we consider each digit position. In the units place, 7 occurs once every 10 numbers (from 7 to 767, skipping 17, 27, etc.), so 76 times. In the tens place, 7 also occurs once every 10 numbers (from 70 to 739, skipping 170, 270, etc.), so another 76 times. In the hundreds place, 7 occurs in every 100 numbers (from 700 to 763), so 6 times. Thus, the total number of times 7 occurs is 76 + 76 + 6 = 158 times.

Math question: What is the sum of the digits in the number 763?

To find the sum of the digits in 763, we break down the number into its constituent digits: 7, 6, and 3. Adding these digits together gives us 7 + 6 + 3 = 16. Therefore, the sum of the digits in the number 763 is 16.

Math question: If 763 is divided by 7 and then multiplied by 4, what is the result?

To find the result, first divide 763 by 7, which equals 109. Then, multiply 109 by 4 to get the final answer. Therefore, the result is 436.
