Jack crawled 3 ft and Christine crawled 3⁄4 the distance Jack crawled. If you add the distance they each crawled together, what

LUCKY_DIMON [66]

Christine crawled:
3 ft* (3/4)= 2.25 ft.

3 ft+ 2.25 ft= 5.25 ft

We already know that 1 ft= 12 in.

5.25 ft* (12in/ 1 ft)= 63 in.

The total distance the two children crawled together is 63 in~

Expanded form of 680,705

denis23 [38]

$\huge\boxed{600,000 + 80,000 + 700 + 5}$

To find expanded form, we need to split up the digits. When you do that, you take one digit and cut off everything to the left of it, then make everything to the right zeros.

$600,000 + 80,000 + 0 + 700 + 0 + 5$

We don't need to keep the zeros.

$\boxed{600,000 + 80,000 + 700 + 5}$

We can check this by adding the numbers back up to get $680,705$ .

$680,000 + 700 + 5$

$680,700 + 5$

$680,705$
