Question

unit place of 5.05+0.2​

Answer 1

Answer:

5.05+0.2=5.25 and its unit place is 5

Step-by-step explanation:

unit place in decimal is the place that takes place at left side of point

Answer 2

Answer:

Hence, the value of unit digit of the sum will be 5

Step-by-step explanation:

In context to questions asked

We have to determine the value of unit place when 5.05 is added to 0.2

As here,

both the number have uneven number of digits after decimal.

So for determining the sum first we need to equalise the number of digits after decimal in case of both the number.

As we know that

If we put extra zero after decimal in any number then it doesn't change the value of the number.

So we can write 0.2 as 0.20

Now adding the given number

For determining the sum we will add the number which are place before decimal together and the number which are after decimal together.

Thus we will get it as,

$5.05 + 0.20 \\ = (5 + 0) + (0.05 + 0.20) \\ 5 + 0.25 \\ = > 5.25$

As we have to find the unit digit of the sum,

So unit digits of the sum will be 5
