Question

8/1-9/2-9/4 simplify it​

Answer 1

The value of the expression $\frac{8}{1}-\frac{9}{2}-\frac{9}{4}$ is 1.25.

Step-by-step explanation:

The expression is: $\frac{8}{1}-\frac{9}{2}-\frac{9}{4}$

Simplify the expression as follows:

$\frac{8}{1}-\frac{9}{2}-\frac{9}{4}=\frac{32-18-9}{4}$

               $=\frac{5}{4}$

               $=1.25$

Thus, the value of the expression $\frac{8}{1}-\frac{9}{2}-\frac{9}{4}$ is 1.25.

Answer 2

Answer:

To solve this question:

8/1 - 9/2- 9/4

Step-by-step explanation:

You need to follow BODMAS rule where B stands for Bracket, O for Of, D for Division, M for Multiplication, A for Addition, and S for Subtraction.

It says that algebraic operations will be performed on letter that comes first, then move to second, then third and so on.

If any letter is absent then we automatically moves to the next letter and that will be our first operation.

There are two ways for solving this question:

Solution 1:

In the above question only two operations are mentioned:  Division and Subtraction.

According to BODMAS rule, first we will perform division and finally subtraction.

8/1  - 9/2 - 9/4  = 8 - 4.5 - 2.25     {Division of individual numbers)

                         = 8 - (4.5 + 2.25)

                         = 8 - 6.75

                         = 1.25 or 125 / 100 or 5 / 4

Solution 2:

Take Lowest Common Multiple (LCM) of all the numbers and applying BODMAS rule.

In this case another operation Multiplication is also present.

8/1  - 9/2 - 9/4 = (8 x 4 - 9 x 2 - 9 x 1) / (4)

                        = (32 - 18 - 9) / (4)

                         = (32 - 27) / (4)

                         = 5 / 4 = 1.25
