Basicaly what you need to awnser this problem is to find what equivalency there is between cups of sugar nd cups of butter. to find that you just need to divide one to another :
3/4 ÷ 1/8 =
If you need to divide any number by a fraction , you can just invert the numerator with the denominator and multiply it instead of divide by it. Formula ( a ÷ x/y = a × y/x )
*a, x and y can be represented by any number
Applying this "formula" to our equation:
3/4 ÷ 1/8 is the same thing as 3/4 × 8
3/4 × 8/1 =
The multiply numerator with numerator and denominator with denominator
24/4 which is 24÷4
24÷4 = 6
The awnser is 6
I hope you understood my brief explanation
