Answer: The fifth grade is 86

Step-by-step explanation:

Given that there are five grades, let the missing fifth grade be represented by x:

84 +79 +82 +88 + x /5 = 83.8

333 + x/5 = 83.8

Next, we cross multiply:

333 + x = 83.8 x 5

333 + x = 419

Subtract 333 from both sides of the equation to get the value of x

333 + x - 333 = 419 - 333

x = 86

A customer bought 7.5 pounds of apples from a local produce market. How many ounces of apples did the customer buy?
jeka94
Now if we have 7.5 pounds of apples first we need to convert 1 pound into ounces.

1 pound = 16 ounces.

Now we know how many ounces are in one pound. So lets take the 16 ounces for 1 pound and multiply by the 7 full pounds of apples. This excluding the 1/2 pound of apples.

7 x 16 = 112
(7 being the weight in pounds of the apples, 16 being 16 ounces in one pound, and 112 is how any ounces are in 7 pounds of apples.)

So now we have the amount of ounces in 7 pounds of apples.
But we are not done. We still have the 1/2 pound of apples. So we take 16 being 1 pound of apples and divide it by 2. 

16 divided by 2 = 8

That 1/2 pound of apples = 8 ounces.

So now we have our 7 pounds of apples in ounces (112) and our 1/2 pound of apples in ounces (8)

So we add these back up in ounces

112 + 8 = 120.

So now we can conclude:

7.5 pounds of apples is 120 ounces

Hope this helps!
