Fernando needs a total of 6
Fantom [35]

Answer:

Equation: 6f = 5

Result: 6/5 cup of flour is needed for each batch of bread

Step-by-step explanation:

Given

6 cups of flour makes 5 batches of bread

Required

His much flour is needed for each batch.

Let f represent a cup of flour.

The statement "total of 6 cups of flour to make 5 batches of bread." means that

f + f + f + f + f + f = 5 batches of bread

f * 6 = 5

6f = 5

The above equation will give the number of cup needed for 1 batch of bread.

To do that, we simply divide both sides by 5

6f/5 = 5/5

6f/5 = 1

Hence,

The equation is represented by: 6f = 5

And the result is: 6/5 cup of flour is needed for each batch of bread

The contrapositive of p q is:
Kay [80]
Some symbols are missing. I'm assuming you meant to put in a horseshoe symbol like so p \supset q

If so, then the contrapositive of that would be \sim q \supset \ \sim p which is the final answer. 

The tilde sign \sim means "not" so writing \sim q means "not q" which is the complete opposite of q.
