For a party 20 sandwiches are being made if each sandwich is cut into thirds how many sandwich pieces are there?

2 answers:

6 0

Well let’s simplify the problem.

If we take one sandwich it would be 1: and if we add the fact that for every one sandwich 3 new sandwiches were made, we can make a 1:3 ratio. If for every 1 sandwich there are 3 more sandwiches then we would multiply the beginning amount of 20 sandwiches to both numbers in the ratio so it stays equivalent.

1 x 20 = 20
3 x 20 = 60

So we can say now that the ratio for 20 sandwich pieces there are 60 new sandwich pieces.

The new ratio being 20:60 thus the amount of sandwiches after they were cut in thirds is 60 sandwiches

Answer = 60 sandwiches

There would be 60 sandwich pieces.
20 times 3=60

Given:

The numbers are $\dfrac{3}{5},2,0,1,-0.45, 1.44$ .

To find:

All the values that cannot be probabilities.

Solution:

We know that,

$\text{Probability}=\dfrac{\text{Favorable outcomes}}{\text{Total outcomes}}$

The minimum value of favorable outcomes is 0 and the maximum value is equal to the total outcomes. So, the value of probability lies between 0 and 1, inclusive. It other words, the probability lies in the interval [0,1].

$0\leq \text{Probability}\leq 1$
