First, you multiply the denominator by the whole number. Next, you add the product to the numerator; the total will be your numerator to the improper fraction. Then, put the total sum/numerator over or on top of the denominator. This will give you your equivalent, improper fraction.
Ex.
2 2/5
5×2=10
10+2=12
Put 12 over/on top of 5
=12/5
12/5 is the equivalent improper fraction of 2 2/5

Ex 1  3/2

2 x 1 +3          5
------------  =   -----  =  2.5
     2               2

first denominator times whatever the whole number is then add that to the nominator than you have an improper fraction

because 3/2 = 1.5 then plus the whole number which is 1.0 = 2.5

If you take half my age and add 7, you get my age 13 years ago. How old am I?
mestny [16]

Answer:

You are currently 40 years old

Step-by-step explanation:

Let's say the current age is represented by the variable x.

x = current age

The question says that "if you take half my age and add 7, you get my age 13 years ago"

This can be represented like this:

1/2(x) + 7 = x - 13

Now we solve for x using basic algebra:

1/2(x) = x - 20

-1/2(x) = -20

x = 40

To check if this is correct, plug it back into the equation and see if both sides equal each other:

1/2(40) + 7 = (40) - 13

20 + 7 = 27

27 = 27

Hope this helps (●'◡'●)
