So,
To find the expanded form, split the number into each place value.
11,760,825
10,000,000 (ten million) + 1,000,000 (one million) + 700,000 (seven hundred thousand) + 60,000 (sixty thousand) + 800 (eight hundred) + 20 (twenty) + 5 (five)
10,000,000 + 1,000,000 + 700,000 + 60,000 + 800 + 20 + 5
Your problem is:
$35.00 is what percentage of $437.50?
If you are given a part and the whole, and you want to know what percent the part is of the whole, divide the part by the whole and multiply by 100.
In this case, the whole is $437.50.
The part is $35.00.
35/437.5 * 100 = 8%
Ok,
f(0.35)= 7f/20
f(-5.2)=-26f/5
f(10)= 10f
f(-0.5)= -f/2
as for the last question I am not quite sure, sorry....hope I helped a little :)
