Answer:

5. thirty-four thousand five hundred

6. seven hundred three and two hundred forty-six thousandth

7. seventy-six million eighty thousand

Step-by-step explanation:

These are the answers because:

1) Word form is translating the numbers into words

2) Basically, all you have to do is write the word form the way you pronounce the number

3) Whenever you are round decimals, make sure to have an "and" for the decimal point and "ths" at the end of the value of the number (look at question 6 for reference)

Hope this helps!
