Abigail is baking a cake. She requires flour and
sugar in the ratio 5:2. If she uses 2 1/2 kg of flour
how much sugar is required?

The answer to your question is 1 kg of sugar

Step-by-step explanation:

Data

ratio flour: sugar  5:2

amount of flour = 2 1/2

amount of sugar = ?

Process

1.- Convert the amount of flour to an improper fraction

            2 1/2 = (4 + 1) / 2

                     = 5/2

2.- Write the problem as a proportion

             5 : 2 :: 5/2 : s     s = amount of sugar

3.- Solve the proportion for x

            x = (2 x 5/2) / 5

-Simplify

            x = (10 / 2) / 5

            x = 10 / 10

-Result

            x = 1 kg  

answer:

step-by-step explanation:

here, the total dishes = 10

dishes having meat = 3 ( chicken, meatloaf and hamburger )

thus, the probability of having meat on the chosen dishes = number of dishes having meat / total dishes

=

therefore, the probability of not having meat = 1- the probability of having meat on the chosen dishes

=

=

=

⇒ option b is correct.
