Question

Joshua wrote down 1 to 30, how many times did he write the number 1?

a. 3
b. 10
c. 11
d. 12

Answer 1

When writing the numbers from 1 to 30, the number 1 appears a total of 12 times, counting every instance in the tens and units places throughout the sequence.

Step-by-step explanation:

The question is asking how many times the number 1 appears when Joshua writes down the numbers from 1 to 30. To find the answer, we list the numbers and count how many times '1' appears:

• The number 1 appears once in the numbers 1, 10, and 20.
• It appears twice in the number 11.
• And once in 12, 13, 14, 15, 16, 17, 18, and 19.

Adding these up, we see that the number 1 appears 12 times:

• 1 (for the number 1)
• 1 (for the number 10)
• 2 (for the number 11)
• 1 each for numbers 12 through 19 (8 times)
• 1 (for the number 20)

Thus, the correct answer is d. 12.

Answer 2

Its d. 12 but if were being realistic its 13 because 11 has two 1's.
