Evaluate \dfrac jk -0.2k k j ​ −0.2kstart fraction, j, divided by, k, end fraction, minus, 0, point, 2, k when j=25j=25j, equals, 25 and k=5k=5k, equals, 5.

Answer 1

Answer:

After evaluating the given expression we get the value as 4.

Step-by-step explanation:

Given:

$\frac{j}{k}-0.2k$

We need to evaluate the expression when j =25 and k =5

Solution:

On substituting the values of k and j in the expression we get;

$\frac{25}{5}-0.2\times5$

We will use PEDMAS which means first operation performed will be division.

So we can say that;

$5-0.2\times5$

Now next Operation to be performed is multiplication.

So we can say that;

$5-1$

Finally we will use subtraction operation and then we will get;

$4$

Hence After evaluating the given expression we get the value as 4.
