How do you turn 12/15 and 68/80 into a decimal and into a percent

Answers

Answer 1

Answer: $(12)/(15)\n\ndivide\ a\ numerator\ and\ a\ denominator\ by\ 3\n\n12:3=4;\ 15:3=5\n\ntherefore\ (12)/(15)=(4)/(5)\n\nmultiply\ a\ numerator\ and\ a\ denominator\ by\ 2\n\n4\cdot\ 2=8;\ 5\cdot2=10\n\ntherefore\ (12)/(15)=(4)/(5)=(8)/(10)=\boxed{0.8}\Rightarrow0.8\cdot100\%=\boxed{80\%}$

$(68)/(80)\n\ndivide\ a\ numerator\ and\ a\ denominator\ by\ 4\n\n68:4=17;\ 80:4=20\n\ntherefore\ (68)/(80)=(17)/(20)\n\nmultiply\ a\ numerator\ and\ a\ denominator\ by\ 5\n\n17\cdot\ 5=85;\ 20\cdot5=100\n\ntherefore\ (68)/(80)=(17)/(20)=(85)/(100)=\boxed{0.85}\Rightarrow0.85\cdot100\%=\boxed{85\%}$

Answer 2

Answer: $\frac{\big{12}}{\big{15}}= \frac{\big{3\cdot4}}{\big{3\cdot5}}= \frac{\big{4}}{\big{5}}= \frac{\big{4\cdot2}}{\big{5\cdot2}}= \frac{\big{8}}{\big{10}}=0.8 \n\n1\%\ \ \rightarrow\ \ 0.01\ \ \ \ \ \ \Rightarrow\ \ \ \ \ 10\%\ \ \rightarrow\ \ 0.01\cdot10=0.1\n\n0.8=8\cdot0.1 \ \rightarrow\ \ 8\cdot10\%=80\%\n\n--------------------\n\n$

$\frac{\big{68}}{\big{80}}=\frac{\big{4\cdot17}}{\big{4\cdot20}}=\frac{\big{17}}{\big{20}}=\frac{\big{17\cdot5}}{\big{20\cdot5}}=\frac{\big{85}}{\big{100}}=0.85\n\n0.85=0.8+0.05=8\cdot0.1+5\cdot0.01\n\n0.85\ \ \rightarrow\ \ 8\cdot10\%+5\cdot5\%=80\%+5\%=85\%$

What is 7/100 as a percent

Answers

7/100 would be 7% if you were doing 7/10 it would be 70%

7/100 as a percent is 7%.

% means out of one hundred so 7% would mean 7 out of 100.

Hallie has 10 times as many pages to read for her homework assignment as janet. Altogether, they have to read 264 pages. How many pages does each girl have to read?

Answers

Since Hallie had 10times as many pages that Janet had, Hallie would be represented as 10xand Janet would be represented just as x, so 10x + x = 264
11x = 264then divide both sides of the equals sign by 11 to get x by itself, so x= 24, so Janet read 24 pages for her homework assignment, while 24 * 10= 240, while Hallie read 240 pages for her homework assignment, and tocheck if the answer is correct, 240 is 10 times larger than 24, and 240 +24 = 264.

Answers

Let the unknown be x. (x/3)-8=46
To then solve this you add 8 to both sides x/3=54
Then multiply both sides by 3 x=162

Dependent variable and independent variable

Answers

The independent variable is the number you put into a function.
The function has no control or influence on it. It's whatever YOU
decided to put in. It's completely independent of the function.

The value that results from what you put in is the dependent variable.
It depends on => what you put in, and => what the function does
with that.

Write 4x24 as distributive property

Answers

Let's check the distributive property first :

$a(b+c)=ab+ac$

where $a$ , $b$ , and $c$ are real numbers.

Now, to express 4x24 in the form $a(b+c)=ab+ac$ , we just need to express 24 as a sum or subtraction.

Notice that we can express a 24 as a sum or subtraction in a number of ways:

1. 24-12=12, so 12+12=24

2. 24-10=14, so 10+14=24

3. 28-4=24, so 28-4=24

And so on...

Now let's use the distributive property:

1. $4*24=96$

Since 24=12+12, we can express the same multiplication using the distributive property as:

$4(12+12)=4*12+4*12=48+48=96$

2. $4*24=96$

Since 24=10+14, we can express the same multiplication using the distributive property as:

$4(10+14)=4*10+4*14=40+56=96$

3. $4*24=96$

Since 24=28-4, we can express the same multiplication using the distributive property as:

$4(28-4)=4*18-4*4=112-16=96$

As you can see, there are many ways to use the distributive property.

4 x 24 =

4 x 20 = 40
4 x 4 = 16

40 + 16 = 56
4 x 24 = 56
