Hey there!
When we multiply fractions and whole numbers, we simply take that whole number and put it over them, and just multiply across. That gives us:
![\frac{1}{2}x*8 = \frac{8}{2} = 4](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B2%7Dx%2A8%20%3D%20%5Cfrac%7B8%7D%7B2%7D%20%3D%204)
Notice how it's four, because when we have a fraction, we divide. 8 divided by 2 equals four. Next:
![\frac{1}{4} *4 = \frac{4}{4} = 1](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B4%7D%20%2A4%20%3D%20%5Cfrac%7B4%7D%7B4%7D%20%3D%201)
4/4 is equal to 1 because 4 divided by 4 is one. 4 goes into 4 once. Next, we have:
![\frac{1}{3}*6 = \frac{6}{3} = 2](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B3%7D%2A6%20%3D%20%5Cfrac%7B6%7D%7B3%7D%20%3D%202%20)
That's because 6/3 = 2.
Hope this helps!
