I help you get correct !
The easiest way to solve this is to write the words mathematically. You're told that the product of 4 and a number, b = 3/5.
That means:
4b (product of 4 and b) =
![\frac{3}{5}](https://tex.z-dn.net/?f=%20%5Cfrac%7B3%7D%7B5%7D%20)
To solve for b, you want to divide both sides by 4 to get the b by itself on the left of the equation:
![4b = \frac{3}{5}\\ \frac{4b}{4} = \frac{\frac{3}{5}}{4}\\ b = \frac{3}{20}](https://tex.z-dn.net/?f=4b%20%3D%20%5Cfrac%7B3%7D%7B5%7D%5C%5C%0A%20%5Cfrac%7B4b%7D%7B4%7D%20%3D%20%20%5Cfrac%7B%5Cfrac%7B3%7D%7B5%7D%7D%7B4%7D%5C%5C%0Ab%20%3D%20%20%5Cfrac%7B3%7D%7B20%7D%20%20)

Answer: b = 3/20
Hope this helps! Have a good day
