Question

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

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

Explanation:

Given:

`(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;

`(25)/(5)-0.2*5`

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

So we can say that;

`5-0.2*5`

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.
