Answer:

turn into top heavy fractions to start off.

whole number X denominator plus numerator

1 X 10 + 3= 13/10

2 X 5 + 2 = 12/5

now need to find a common denominator we can use 10.

5 X 2 = 10 what you do to the bottom you must do to the top.

12 X 2 = 24

the sum should now read

13/10 + 24/10 = 37/10.

to turn back into mixed number work out how many denominators go into numerator.

in this case 3. whatever is left over becomes the numerator. end answer 3 7/10

A gardener has a container with 6 1/5 ounces of liquid plant fertilizer on Sunday the gardener uses 2 1/2 ounces on a flower gar

sergey [27]

Amount of liquid plant fertilizer in the container that the gardener has = 6 1/5 pounds
   = 31/5 pounds
We already know that 1 pound = 16 ounce
Then
Amount of liquid plant fertilizer in the
container that the gardener has = (31/5) * 16 ounce
= 496/5 pounds
Amount of liquid plant fertilizer that the gardener uses on Sunday = 2 1/2 ounces
   = 5/2 ounces
Then
The amount of liquid plant fertilizer that are left= (496/5) - (5/2) ounces
   = (992 - 25)/10 ounces
   = 967/10 ounces
   = 96.7 ounces
So the total amount of liquid plant fertilizer left is 96.7 ounces.

In a class of P students, the average of test scores is 70. In another class the average test scores is 92. When scores of the t

Basile [38]

So, since averages are defined as:

$\frac{\sum_{k=1}^{P} P_k}{P}=70$

So, since P are the total number of elements and P_k is the P_kth student. This is saying if we sum over each student's score and divide it by the number of students, we should get P, which is true.

So, using that logic, the other class can be represented as:

$\frac{\sum_{k=1}^{N} N_k}{N}=70$
