Hello there! How are you today?
First, let's take a look at our numbers.
45 / 100
Both of these numbers have a 0 and a 5, which means it is divisible by 5.
Let's divide both of them by 5.
45 / 5 = 9
100 / 5 = 20
We are now left with 9/20.
This is your simplified fraction since 9 and 20 do not have any common factors.
I hope this helps!

Step-by-step explanation:
Answer:
Original number 26.
Step-by-step explanation:
xy - two-digit number
1) x + y = 8
2) Original two-digit number can be written as
10*x + y
3) If the digits interchanged yx,
then the new number can be written as
10*y + x
4) Double the original number is
2*(10*x + y)
5) New number is 10 more than double the original number
(10*y + x) - (2*(10*x + y)) = 10
6) Now we have the system of 2 equations:
x + y = 8
(10*y + x) - (2*(10*x + y)) = 10 -----> 10y + x - (20x + 2y) = 10 ---> 8y - 19x = 10
x = 8 - y
8y - 19(8 - y) = 10
8y - 152 +19y = 10
27y = 162
y = 6
x = 8 - y = 8 - 6 = 2
x = 2
So, x =2, y = 6.
Original number 26.

Original number 26.
New number 62.
Double of the original number = 2*26= 52.
New number is 10 more than double the original number :
62 - 52 = 10 True
Answer:
x = 5
Step-by-step explanation:
If x + 5 = 10, then x would have to be 5 because 5 + 5 = 10.
The way you would solve this would be:
x + 5 = 10
subtract 5 from both sides of the equation
x + 5 - 5 = 10 - 5
simplify:
x = 5
