Answer: 1 1/2
You can write this as 1 & 1/2
The whole part is 1. The fractional part is 1/2
==========================================================
Explanation:
Let's say we had 18 cookies to hand out to 12 students.
How many cookies does each student get?
Using a calculator shows that 18/12 = 1.5 which means they get one whole cookie each
The leftovers is 18-12 = 6
Then notice how 6/12 = 1/2
So that's how the improper fraction 18/12 becomes the mixed number 1 & 1/2
So each student gets 1 full cookie, plus half a cookie.
------------------
Or we could do the problem like this
18/12 = (12+6)/12
18/12 = (12/12)+(6/12)
18/12 = 1 + (1/2)
18/12 = 1 & 1/2

Answer:</h2>
7.5cm2
<h2>
Step-by-step explanation:</h2>
5x3cm=15cm2 because of base x height/2 you would do
15cm2 divided by 2 since it is a triangle (a half of a square) which is 7.5cm2
The first book you select can be any one of 700.
. . . For each of those ...
The second book can be any one of the other 699.
. . . For each of those ...
The third book can be any one of the remining 698.
The total number of ways to gather three books from the shelves into your hands is (700 · 699 · 698) = <em>341,531,400 ways</em> .
<em>BUT ...</em>
When you bring three books to the check-out counter, Marian the Librarian doesn't know in which order you took them down off the shelves. You could have gathered the same three books in (3 · 2 · 1) = 6 different ways.
So, even though there are 341,531,400 ways to<em> </em>gather up three books, there are only (341,531,400 / 6) = 56,921,900 different GROUPS of three books that you can choose to take home.
Answer:
The value of 
- 
is 3 ⇒ 2nd
Step-by-step explanation:
The dimensions of any matrix are (m × n), where
- m is the number of its row
- n is the number of its column
Ex: Matrix A of dimensions (2 × 3) has 2 rows and 3 columns, where
means the element in the 1st row and 1st column
means the element in the 1st row and 2nd column
means the element in the 1st row and 3rd column
means the element in the 2nd row and 1st column
means the element in the 2nd row and 2nd column
means the element in the 2nd row and 3rd column
Now lets solve the problem
∵ The matrix B has 3 rows
∴ m = 3
∵ The matrix B has 4 columns
∴ n = 4
∴ The dimensions of matrix B are (3 × 4)
∵ means the element in the 2nd row and 4th column
∴ = 9
∵ means the element in the 3rd row and 2nd column
∴ = 6
- Find the value of -
∵ - = 9 - 6
∴ - = 3
