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:

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

Amy bought a bag of chips for 0.75, a sandwhich for 5.50, a bottle of water for 1.60. How much does amy have left from 10.

ch4aika [34]

Answer:

Amy would have 2.15 left

Step-by-step explanation:

To find out how much she has left, subtract the cost of the items from 10.

10 - 0.75 - 5.50 - 1.60 = 2.15

A garden is designed in the shape of a rhombus formed from 4 identical 30°-60°-90° triangles. The shorter distance across the mi

EleoNora [17]

Answer:

c) 120 ft

Step-by-step explanation:

Let's consider the rhombus has 4 sides, A, B, C, and D.

To find the length of each side, let's first find the length AE.

From the diagram, AE is half of AC and AC = 30 ft.

Therefore,

AE = ½ * 30

AE = 15 ft

Let's find the length AD, since we are looking for the distance around the perimeter.

$AD = \frac{15}{sin30} = \frac{15}{0.5} = 30 ft$

We are told the rhombus is formed by four identical triangles.

Therefore the distance around the perimeter would be: AD+AD+AD+AD=

30 ft + 30 ft + 30 ft + 30 ft

= 120 ft

The distance around the perimeter of the garden is 120 ft
