Question

20. What should be added to the difference of 4.15 and 1.674 to get 9?
​

Answer 1

Answer:

6.524

Step-by-step explanation:

First, we will find the difference of 4.15 and 1.674

Since both these numbers are not made up of the same no. of digits, so we would make their decimal places equal.

For this, we will add a 0 to 4.15 to make it 4.150

Now, both the numbers have 3 decimal places...So now we can find the difference:

4.150 - 1.674 = 2.476

Now, we have to add a number to 2.476, to get 9.

For this, we will just subtract 2.476 from 9.

We will again make the decimal places equal by putting three zeroes after 9.

So we get 9.000 which is also  equal to 9.

So, 9.000 - 2.476 = 6.524,

Therefore,

We have to add 6.524 to 2.476, to get 9.
