D. 16/20

Answers

Answer 1
Answer: 9/13 is not a fraction that can be simplified: the two numbers don't have a divisor in common.

Let's bring all the other fractions into their simplest form too:

A.6/10=3/5
B. 2/3 This is the simplest form already
C.36/52 =18/26=9/13 ( I divided both numbers by 2 each time)


.... and we don't have to look further, we have already found the right answer: 9/13 is equivalent to 36/52.

okay so 0.4 is equal to 4/10 (hopefully you know that!) & anything over 1 is itself so i would but 64 over 1.

so now you hace 2 fractions & when dicing fractions you alwas flip the second fraction upside down & then just multiply across.

so if you have
64 4
---- / ----
1 10

you would switch the 2nd one so the 10 would be on top.

so that would give you 64*10 over 1*4

which equals 640/4

& when you simplify that you get 160

so that's your answer(:

33.52 is what percent of 8

Answers

The Solution for 33.52 is 419% of 8.

Since we know that percent shows per 100 (since cent means 100), thus we will first divide the whole part into 100 parts and then multiply it with b so that we collect b items per 100 items(that is exactly what b percent means).

100% / x% = 8 /33.52

(100/x)*x =(8/33.52)*x      

Here we multiply both sides of the equation by x

100=0.238663484487x      

Now we divide both sides of the equation by (0.238663484487) to get x

100/0.238663484487=x

419=x

x=419

now we have, 33.52 is 419% of 8

1. We assume, that the number 8 is 100% - because it's the output value of the task. 
2. We assume, that x is the value we are looking for. 
3. If 100% equals 8, so we can write it down as 100%=8. 
4. We know, that x% equals 33.52 of the output value, so we can write it down as x%=33.52. 
5. Now we have two simple equations:
1) 100%=8
2) x%=33.52
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
100%/x%=8/33.52
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 33.52 is what percent of 8

100%/x%=8/33.52
(100/x)*x=(8/33.52)*x       - we multiply both sides of the equation by x
100=0.238663484487*x       - we divide both sides of the equation by (0.238663484487) to get x
100/0.238663484487=x 
419=x 
x=419

now we have: 
33.52 is 419% of 8
