Question

1/2 tsp of salt makes 16 cookies. how many salt would you need for 55 cookies?

Answer 1

`(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 2

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.
