So,

#1: $\frac{5}{8}$

We know that $\frac{1}{8}$ = 0.125, or 12.5%.
Therefore, we just have to multiply 12.5% by 5 to get $\frac{5}{8}$ in percent form.

12.5(5) = 62.5

$\frac{5}{8}$ as a percent is 62.5%.

#2: $2 \frac{4}{7}$

$2 \frac{4}{7} = 200%$ + $\frac{4}{7}$

4/7 rounded to the nearest thousandth is 0.5714, or 57.14%.

200% + 57.14% = 257.14%

Lilly took out an 80/20 mortgage to buy a house costing $100,000. The first

adoni [48]

Answer:

$442.1 per month

Step-by-step explanation:

Lilly took 80/20 mortgage to buy house costing $ 100000

80% × 100000 = 80000 for the first at 4.75%

80000 × 4.75% = 80000 × 0.0475 = $ 3800 as interest per year,

20% × 100000 = 20000 for the second mortgage

20000 × 7.525% = 20000 × 0.07525 = 1505 as interest per year

add the first interest and the second interest

3800 + 1505 = 5305

divide the answer by 12 months to find the monthly payment

5305 / 12 = $442.1 per month

You can use 1 of 2 methods to solve this problem. You can either solve it traditionally or by just looking at it (you don't necessarily need to convert it to scientific notation to find the answer).

{METHOD 1}- Traditional Method

Scientific Notation is just another way of writing REALLY BIG or REALLY SMALL numbers in a simplified manor

Let's take 232,000,000 for instance

First you want to find your decimal number. Your decimal number has to be Greater than 1 and less than 10.

In this case your decimal number will be 2.32

Then let's could how many decimal places are to the RIGHT of 2.32
Keep in mind that if the number is very small you have to count the decimal places to the LEFT

{METHOD 2}

If you look at 232,000,000 and 2,320,000,000 you can tell that 2,320,000,000 is longer just by looking at it, so you can determine that ....

232,000,000 = 2.32E8
2,320,000,000=2.32E9

Using the same method you can solve the last two.

0.00000431 is a larger number than 0.000000000000431. So you can then determine that.....

0.00000431= 4.31E-6
0.000000000000431=4.31E-13
