Let's solve each part of the worksheet step by step.

---

A. Write the numbers in STANDARD FORM

#### i. $ 90,000 + 1,000 + 600 + 10 + 6 $

We add all the values together:

- $ 90,000 $
- $ + 1,000 = 91,000 $
- $ + 600 = 91,600 $
- $ + 10 = 91,610 $
- $ + 6 = 91,616 $

✔ Answer: 91,616

#### ii. *three hundred twenty-one million eight hundred sixty thousand four hundred fifteen*

Break it down:

- "three hundred twenty-one million" → 321,000,000
- "eight hundred sixty thousand" → 860,000
- "four hundred fifteen" → 415

Now add them:

- $ 321,000,000 + 860,000 = 321,860,000 $
- $ + 415 = 321,860,415 $

✔ Answer: 321,860,415

- $ 6,000,000 $
- $ + 50,000 = 6,050,000 $
- $ + 7,000 = 6,057,000 $
- $ + 300 = 6,057,300 $
- $ + 90 = 6,057,390 $

B. Write the numbers in EXPANDED FORM

#### i. $ 418,952,302 $

Break this number into place values:

- Hundreds millions: 400,000,000
- Ten millions: 10,000,000
- Millions: 8,000,000
- Hundred thousands: 900,000
- Ten thousands: 50,000
- Thousands: 2,000
- Hundreds: 300

So:

$ 400,000,000 + 10,000,000 + 8,000,000 + 900,000 + 50,000 + 2,000 + 300 + 0 + 2 $

But we can simplify:

✔ Answer: $ 400,000,000 + 10,000,000 + 8,000,000 + 900,000 + 50,000 + 2,000 + 300 + 2 $

(We skip tens since it's 0.)

- Billions: 0
- Millions: 910 million → "nine hundred ten million"

#### ii. $ 80,000,000 + 1,000,000 + 300,000 + 50,000 + 8,000 + 200 + 10 $

Add them first to get standard form:

- $ 80,000,000 $
- $ + 1,000,000 = 81,000,000 $
- $ + 300,000 = 81,300,000 $
- $ + 50,000 = 81,350,000 $
- $ + 8,000 = 81,358,000 $
- $ + 200 = 81,358,200 $
- $ + 10 = 81,358,210 $

Now write in word form:

- 81 million → "eighty-one million"
- 358 thousand → "three hundred fifty-eight thousand"
