21 is (66 and 2/3)% of what number?
I believe the answer is 14.
is it right?
No. 14 is 66 2/3 of 21
0.666667x = 21
Your answer will be more than 21.
this is confusing :(
this is how I am solving.
66 2/3 12
------- = -----
100 W
so i mulitiplyed 100x12= 2100.
and from here I don't know how to insert 66 2/3 into calculator.
2100 divided by 66.667?
the choice to answers are
14, 3.17, 315 and 31.5
I know for sure that 14 is not the answer. i get different answers everything i play with that 2/3. please help
66 2/3% = 200/300 = 2/3
so just like Ms Sue stated ...
(2/3)x = 21
times 3
2x = 63
divide by 2
x = 31.5
Where did you get the 12 from in your solution?
(dyslexia) ??
had your ratio been:
(66 2/3) / 100 = 21/w
it would have worked:
(200/3) / 100 = 21/w
(200/3)w = 100(21)
(200/3)w = 2100
times 3
200w = 6300
w = 6300/200 = 31.5
0.666667x = 21
x = 21/0.666667
x = 31.5
oh, okay.
now I get it. thanks!!!
You're welcome.
I'm glad you've got it. :-)
To find the number that 21 is 66 and 2/3% of, you can use the formula:
Number = (Percentage / 100) * Value
In this case, the percentage is 66 and 2/3% which can also be written as 66.67%.
Let's substitute the values into the formula:
Number = (66.67 / 100) * Value
Now we can solve for the value:
21 = (66.67 / 100) * Value
To isolate the Value, we divide both sides of the equation by (66.67 / 100):
21 / (66.67 / 100) = Value
To simplify the calculation, we can first convert the division into multiplication by flipping the fraction:
21 * (100 / 66.67) = Value
Now we can calculate this expression to find the Value:
21 * (100 / 66.67) ≈ 31.5
Therefore, the number that 21 is 66 and 2/3% of is approximately 31.5, not 14.
