Fred is making a fruit salad. The ratio
of cups of peaches to cups of cherries
is 2 to 3. How many cups of peaches
will Fred need to make 60 cups of
fruit salad?

24 cups

Step-by-step explanation:

Peaches to Cherries is given as 2 to 3

We can think of this as "parts". So total parts in the salad would be:

Total Part = 2 + 3 = 5 parts

So, now we need cups of peaches to cups of TOTAL

The ratio would be:

2 : 5

The total would be 60 cups

We let total cup of peaches be x

So we can write the ratio:

Now, we cross multiply and solve for x:

Fred will need 24 cups of peaches

a framing bias

step-by-step explanation:

rodrigo is subject to a framing bias i believe.

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )
