Question

I’m having trouble with my hw and I’m stressing out.

Answer 1

Explanation:

Let x teaspoons of salt would be required.

`\therefore (3)/(4) : 1 (1)/(8) : : 1 : x = (3)/(4) : (9)/(8) : : 1 : x \\ \\ \therefore \: ( (3)/(4) )/( (9)/(8) ) = (1)/(x) \\ \\ \therefore \: (3)/(4) * x = 1 * (9)/(8) \\ \\ \therefore \: x = (9)/(8) * (4)/(3) \\ \\ \therefore \: x = (3)/(2) * (1)/(1) \\ \\ \therefore \: x = (3)/(2) \\ \\ \huge \red{ \boxed{\therefore \: x = 1(1)/(2) }}`

Therefore,
`1(1)/(2)` teaspoons of salt would be required when 1 cup of flour is used.
