# Thread: Divide Frac by whole numb 2

1. ## Divide Frac by whole numb 2

Another Fraction divided by whole number. My answer is 54 but somehow I doubt that's right.

Question
2 1/3 : 18 = ?

2 1/3 2x3= 6 + 1 = 7
7/3 : 18 = 7/3 : 18/1 = 0/3 x 1/18 = 0/54

Another Fraction divided by whole number. My answer is 54 but somehow I doubt that's right.

Question
2 1/3 : 18 = ?

2 1/3 2x3= 6 + 1 = 7
7/3 : 18 = 7/3 : 18/1 = 0/3 x 1/18 = 0/54
where'd the 0/3 come from?

remember the lesson learned here http://www.mathhelpforum.com/math-he...hole-numb.html

(2 1/3)/ 18 = (7/3)/(18/1) = (7/3)*(1/18) = 7/54

Another Fraction divided by whole number. My answer is 54 but somehow I doubt that's right.

Question
2 1/3 : 18 = ?

2 1/3 2x3= 6 + 1 = 7
7/3 : 18 = 7/3 : 18/1 = 0/3 x 1/18 = 0/54
$\displaystyle 2\frac{1}{3} \div 18 = \frac{7}{3} \div \frac{18}{1} = \frac{7}{3} \times \frac{1}{18} = \frac{7\times1}{3\times18} = \frac{7}{54}$

4. ## 42

Hmm...I think it's 42. Just reply and I'll explain for you if you like

5. ## Oops, did the earlier one wrong. -.-

I decided to explain anyway. And I found I did the one earlier wrong. -.- sorry about that. lol, this is how I did it:
Convert 2 1/3 into an irregular fraction:
7/3
Convert 18 into a fraction:
18/1
Change division to multiplication and use the reciprocal of 18/1 (flip it around):
7/3 X 1/18=7/54
Yeah, so it's 7/54.
