Levi wants to order the fractions 1/3, 2/5, and 11/30 in descending order? How can you help him by using a common denominator? E

Georgia [21]

Answer:

The correct order of fractions in descending order will be:

$\frac{2}{5}, \frac{11}{30}, \frac{1}{3}$

Step-by-step explanation:

Given fraction:

$\frac{1}{3}, \frac{2}{5}, \frac{11}{30}$

To arrange them in descending order.

Solution:

In order to arrange the fractions in descending order, we will have to find the least common denominators.

To find the least common denominator, we will find the least common multiple of the denominators 3,5, and 30.

Since 30 is a common multiple of all 3 numbers, so it will be the least common denominator.

So, we multiply the numerators and denominators with same numbers in order to make the denominators = 30.

So, we have:

$\frac{1}{3}, \frac{2}{5}, \frac{11}{30}$

⇒ $\frac{1\times 10}{3\times 10}, \frac{2\times 6}{5\times 6}, \frac{11\times 1}{30\times 1}$

⇒ $\frac{10}{30}, \frac{12}{30}, \frac{11}{30}$

Now, we compare the numerators and arrange them accordingly.

$\frac{12}{30} > \frac{11}{30} > \frac{10}{30}$

So, the correct order of fractions in descending order will be:

$\frac{2}{5}, \frac{11}{30}, \frac{1}{3}$

A person invests 9000 dollars in a bank. The bank pays 4.75% interest compounded quarterly. To the nearest tenth of a year, how

solong [7]

7.1 years

Step-by-step explanation:

Principle P = 9000 dollars

Rate r = 4.75% = 0.0475

Total Amount A = 12600 dollars

compounded quarterly n = 4

Time t = ?

t = ln(A/P) / n[ln(1 + r/n)]

t = ln(12,600/9,000) / ( 4 × [ln(1 + 0.011875/4)] )

t = 7.1 years

so the answer is 7.1 years
