Let x = number of cups of ingredient B if 2 cups of ingredient A are used. Set up a proportion: (1/2)/(1 2/5) = (2)/x. Cross multiplying we get (1/2)x = (1 2/5)(2)
(1/2)x = 14/5, so x = 28/5 = 5 3/5 cups.
Formula a = 2b + c in subject to b is b = a-c / 2
Changing the subject of formula is a way of rearranging formula to determine missing variable in terms of other variable
Changing the subject of formula is also known as rearranging formula or changing the subject of an equation.
Given ,
Formula : a = 2b + c
Subtracting by c on both sides,
=> a - c = 2b + c - c
=> a - c = 2b
Dividing by 2 on both sides,
=>
Formula in subject to b is
b = a-c / 2
