Find 83 2/3 % of 12.6 (or What number is 83 2/3 % of 12.6?)
|
|
The PERCENT always goes over 100.
(It's a part of the whole 100%.)
12.6 appears with the word of:
It's the WHOLE and goes on the bottom.
|
|
We're trying to find the missing PART (on the top).
|
|
In a proportion the cross-products are equal:
So 12.6 times 83 2/3 is equal to 100 times the PART.
|
The missing PART equals 12.6 times 83 2/3 divided by 100.
|
|
(Multiply the two opposite corners with numbers; then divide by the other number.)
|
|
12.6 times 83 2/3 |
= |
100 times the part
|
(126/10)(251/3) |
= |
100 times the part
|
31626/30 |
= |
100 times the part
|
(31626/30)(1/100) |
= |
(100/1)(1/100)( the part)
|
31626/3000 |
= |
the part
|
10542/1000 |
= |
the part
|
10.542 |
= |
the part
|

PLEASE NOTE: There are MANY other ways to do the arithmetic in this problem - hopefully this shows the steps in an understandable manner; it is neither the easiest nor the best approach.
