Answer:
The answer is 270.
Step-by-step explanation:
This is the answer is because:
If you let the number be <em>x</em>.
<em>x </em>divided by 3 is equal to <em>x </em>divided by 10 plus 63.
<em>x</em>/3 = <em>x</em>/10 +63
So...
<em>x</em> divided by 3 plus <em>x </em>divided by 10 is equal to 63
<em>x</em>/3 +<em>x</em>/10 = 63
Then if you make a commmon denominator...
10<em>x </em>divided 30 plus 3<em>x</em> divided by 30 is equal to 63
10<em>x</em>/30 + 3<em>x</em>/30 = 63
Then...
7<em>x </em>divided by 30 is equal to 63
7<em>x</em>/30 = 63
After that...
<em>x</em> is equal to ( 63 * 30 ) divided by 7
<em>x</em> = (63*30) / 7
So...
<em>x</em> is equal to 9*30
<em>x </em>= 9*30
Finally...
<em>x </em>is equal to 270
<em>x </em>= 270
