This is a situation where a "Please" would really help.
In the picture, I see a 12 being divided by 3/5 .
I'm sure you've learned how to divide by a fraction . . . you flip the fraction upside down, and then multiply by it.
So, if you need to divide 12 by 3/5, you'll need to flip the 3/5 upside down, then multiply the 12 by 5/3 .
Are you uncomfortable because you know how to multiply two fractions, but 12 is not a fraction so there's only one fraction here ? Is that what's troubling you, Bunky ?
What if I take the 12 and write it as 12/1 . I haven't changed it at all, but now it looks like a fraction ! So now the problem is: Multiply (12/1) x (5/3) .
Multiply the two numerators to get the numerator of the product.
Numerator is (12 x 5) = 60
Multiply the two denominators to get the denominator of the product.
Denominator is (1 x 3) = 3
So the product is 60/3 .
You could leave it like that. But I don't think the teacher would be happy, because 60/3 is crying out to be simplified.
It's <em>20</em> .
