Question

1. The first number is 34,506. What is 34,506 rounded to the nearest thousand. Explain your answer.

2. The second number is 4,378. Write 4,378 in expanded form. Explain your answer.

Answer 1

1. 34,500, since 5 is in the place next to the thousandth place, that means to round up

2. 4,000+300+70+8-
you take each number out & replace the other number spaces with 0's, since there are 3 numbers after 4, three zeros go in those spaces . since there are 2 numbers after 3, two zeros go in those spaces and so on
