Answer:

3/9

Step-by-step explanation:

So,if they tell you to find a probability between 0-9 you should write down all the numbers from 0-9 and circle the multiples of what they give you.

eg. 0-9 = 0-1-2-3-4-5-6-7-8-9

      multiples of 3 = 3,6,9

then you STOP because they said from 0-9

so your answer is going to be 3 out of (the total numbers included) 9

Shane has 1/2 pound of cheese to make 4 sandwiches. He wants to use the same amount of cheese in each sandwich. What fraction of
anastassius [24]

Answer:

The fraction of one pound of cheese to be used in each sandwich is 1/8

Step-by-step explanation:

Here, we have a question that requires the method of dealing with the division of fractions.

To divide a fraction by a whole number, we multiply the denominator of the fraction by the whole number as follows;

\frac{x}{y} \div z =\frac{x}{y\times z}

Quantity of cheese Shane has = 1/2 pound

Number of sandwiches to be made = 4

Amount of cheese per sandwich = 1/2÷4 = 1/8.
