Answer:

1) 105.5    2) 67,994,000    3) -4.1

Step-by-step explanation:

The place value after the decimal point goes 10th, 100th, 1000th, etc.

For #1, we're asked to round to the nearest 10th. The 10th value is 4. To round it to the nearest 10th, we have to look at the number after that. In this case, it's 9. Since 9 is bigger than 4, the 4 becomes a 5, and all the other decimal points become 0. So, 105.496 rounded to the nearest 10th is 105.5

For #2, we're asked to round to the nearest 10,000s. The 10,000s value in 67,994,374 is 9. The value after that is 4. Since 4 is less than 5, the 4 stays the same but all the other values become 0. So, 67,994,374 rounded to the nearest 10,000s is 67,994,000.

For #3, we're asked to round to the nearest 10th. The 10th value is 0. To round it, the value after that is 5. 5 is equal to five, which means the 0 turns 1, and the other values become 0. So -4.05 rounded to the nearest 10th is -4.1
