Answer:


(55)/(32) tsp

Explanation:

To find out how much salt you would need to make 55 cookies, you need to find how much salt makes 1 cookie:

If
(1)/(2) tsp of salt makes 16 cookies, then (
(1)/(2) ÷ 16) tsp of salt will make 1 cookie.

But how much is
(1)/(2) ÷ 16?

To divide fractions with different denominators easily, use the SFM method:

S - Skip

F - Flip

M - Multiply


(1)/(2) ÷
(16)/(1) First, Skip your focus to the 2nd number. This is what will be changed.


(1)/(2) ÷
(1)/(16) Next, Flip the numerator and denominator.


(1)/(2) ×
(1)/(16) Finally, multiply the two numbers together.


(1)/(32)


(1)/(32) tsp of salt will make 1 cookie.

Now to find the amount needed for 55 cookies:

To find the amount of salt needed to make 55 cookies, multiply
(1)/(32) × 55.


(1)/(32) ×
(55)/(1) =
(55)/(32)

Because the fraction cannot be simplified further, the amount of salt that is needed to make 55 cookies is
(55)/(32) tsp.

Answer:

Step-by-step explanation: 1/2x=16

16x4=64, Although this is not exactly 55 cookies, you can either make more or less. So you need 4 salt, to make 55.
