How is adding mixed numbers with unlike denominators the same as adding fractions with unlike denominators? How is it different?

Sedaia [141]

To add a mixed number you must first convert it into a heavy headed fraction eg. 12/4
Then you must find a common denominator for all of the fractions like you normally do for regular addition of fractions
After you have added them you must convert the heavy headed fraction back into a mixed number by seeing how many times the numerator goes into the denominator

Bogdan [553]

Answer:

<h2>$16,104.35</h2>

Step-by-step explanation:

the expression for compound interest is given as

$A = P(1 + \frac{r}{n})^{nt}$

A=$20,000

P=?

r=7.25%=0.0725

n=52 weeks

t=3 year

$20000= P(1 + \frac{0.0725}{52})^{52*3}\\\\20000= P(1 + \frac{0.0725}{52})^{156}\\\\20000= P(1 +0.00139)^{156}\\\\20000= P(1.00139)^{156}\\\\20000=1.2419P\\\\P=20000/1.2419\\\\P=16104.35\\$

the manager need to invest $16,104.35
