80% as a fraction would be 4/5.
First, change it to 80/100.
Then, simplify: 8/10
Simplify further: (8÷2=4) (10÷2=5)
And you have your answer: 4/5
Hope this helps! :D

Answer:

From left to right, -3/2, -4/5, -3/10, 1/2, 7/8, 4/3

Step-by-step explanation

So what we're trying to do here is to order the numbers from greatest to least.

Let's start off with the negative numbers.

-3/10, -4/5, -3/2.

Now what we want to do is give them all a common denominator to figure out which one is the least of that group.

-3/10,-8/10,-15/10.

Now on to the positive numbers.

1/2, 4/3, 7/8

Turn the denominator into 24.

12/24, 32/24, 21/24

Then put them all in order.

2 3/4 - 1 1/8=?
Airida [17]
Basically you need to make the denominator (whats on the bottom) the same, lets take the first one for example


2 3/4, lets put this all over 4 for the same denominator.

2=8/4, and then add this to 3/4 to get 11/4.

the second part will work the same way,

start by making 1 into 8/8. add this to 1/8 to get 9/8


now we have to add 11/4 and 9/8. to do this, you have to find the smallest multiple between the two (for example: between 6 and 4 it would be 12, since 4*3= 12, and 2*6=12)

now, the smallest common multiple between 4 and 8 would just be 8


11/4= 22/8, since you multiply the bottom and top by the same amount so it still equals 11/4, but your denominator will now be 8.


now you can subtract. 22/8- 9/8= 13/8


final answer: 13/8


try the rest yourself since this is important for later math, hoped this helped :)

drek231 [11]

Answer:

97.7161 {cm}^{3}

Step-by-step explanation:

<h3>Input Data :</h3>

Length = 3.6 cm

<h3>Objective :</h3>

Find the volume of Hemisphere.

<h3>Formula :</h3>

Volume =

\frac{ 2\pi {r}^{3} }{3}

<h3>Solutions</h3>

volume =

<h3>\frac{2 \times 3.1416 \times 3.6 ^{3} }{3}</h3>

\frac{2 \times 3.1416 \times 46.656}{3}

\frac{293.1483}{3}

volume = 97.7161 {cm}^{3}

lbvjy [14]
2*3 = 6 teaspoons per day per child
6*5 = 30 teaspoons 
30*3 = 90 teaspoons 
You need 90 teaspoons

1 teaspoon = 4.9289 mL
90*4.9289 = 443.6010 mL
443.6010 / 150 = 2.9573 bottles

You need at least 3 bottles
