If 37 is 74 percent then what number is 100 percent?

[Mutoh]

50?

Correct. @Boomwebsearch you can "reverse engineer" the question if you think you have the right answer.

 

Take 50, multiply by 74%:

50 * 0.74 = 37

 

So by doing this, we have confirmed that 37 is the correct answer.

 

You can calculate this by doing the following:

 

1.

Take 74% and inverse it:

1 / 0.74 = 1.351351351351351

Most calculators have a "1/x" function to make this faster

 

Then you take the result, and multiply by 37:

1.351351351351351 * 37 = 50

 

There are often rounding errors in these calculations. Technically the above calculation yields 49.9999999 repeating, so you just round to 50.

 

EDIT: there may be a more accurate/easier/faster way to calculate this, but I haven't had math class in like 10 years, so, don't assume this is the method your teacher wants you to use.

I thought that if 50 is 100 percent then 1 would be 2 percent. Then using that in a table you can find out if it applies to 37 is 73 percent which verifies that the answer of 50 is correct.

73% is incorrect though.

 

You can test for yourself:

50 * 0.73 = 36.5

 

It's close, and can be rounded to 37, but 74% is the "more accurate" answer.

Brings me back to my Numerical Analysis course. Them round-off errors.

Yeah I always hated those “reverse the equation” type problems lol

If 37 is 74% all you need to do is divide the number by the percentage.

so to get 100% you just need to do this:

37/74%

or 37/0.74

It'll give you 50

Wow... so much math for such a easy question Let's add some quantum physics calculations in there too

homework questions

 

37 is 74% of 50

 

x times 0.74 = 37

then 37 divided by 0.74 = 50

I quite clearly stated that it might not be the easiest or fastest method

I am guilty of using solver in my graphics calculator for 100% of any math related question my course even just this

Yea I know  It's just your post kinda reminds me of something like this:

To be fair, my phone is literally always on me. Me being in a situation where I need to do math, and I don't have my phone, is incredibly unlikely. Especially if this was part of my job.

That's why I always carry a pen, a pen that can write on almost anything, including steel and sandpaper (not so well).

there you go

 

but those two others wont be able to do squat without their calculator and cell phone.

 

 

lol

 

The other guy is fired

 

and you are hired!!!!!!!!!!

You can actually think!!!!!!!!!!!!!!

Stranded, where? In a farmers field? If I was stranded, why would I be concerned about math (especially if the context is fixing some piece of farmers equipment)?

 

Plus, I always keep a 13,000 mAh battery pack in my backpack

 

So sure, hypothetically there could be a situation in which my battery ran out, and the backup battery ran out, and I had no electricity.

 

But hypothetically, your pencil could break, or you could get a concussion and your internal math skills could be clouded by the injury.

 

I mean, if we're talking about whataboutisms after all
