How to convert improper fractions to a mixed numeral
Deffense [45]
Say for example, you have the improper fraction 18/7
The first step is to find out how many times 7 fits into 18
This looks like flipping the fraction, 7/18 = 2 whole times  with 4 parts left over
The 4 left over gets put in front of the original number (7) to give 2 4/7

To check if you have done it correctly, multiply the whole number (2) by the denominator ( 7 ) and then add the numerator.
2 x 7 = 14 + 4 = 18

Hope this helps

Alyssa is building a brick mailbox. She is going to stack bricks that are each \dfrac23 \text{ft}
aalyn [17]
Given that each of the brick is \frac{2}{3} ft tall and the finished stack of bricks is 4\frac{2}{3} ft tall.

Let the number of bricks in the stack be x, then

\frac{2}{3} x=4 \frac{2}{3} = \frac{14}{3}  \\  \\ \Rightarrow x= \frac{ \frac{14}{3} }{ \frac{2}{3} } = \frac{14}{3} \times \frac{3}{2}  \\  \\ = \frac{14}{2} =7

Therefore, 7 bricks will go in the stack.

If $500 is invested at 8% annual interest, how much will be in the account after 3 years if it's compounded quarterly?
Alchen [17]

Answer:

FV= $634.12

Step-by-step explanation:

Giving the following formula:

Initial investment (PV)= $500

Number of periods (n)= 3*4= 12 quarters

Interest rate (i)= 0.08/4= 0.02

<u>To calculate the future value, we need to use the following formula:</u>

<u></u>

FV= PV* (1 + i)^n

FV= 500*(1.02^12)

FV= $634.12
