Question

Noam solved the equation for k using the following calculations.

Answer 1

Answer:

3) He made a computation error when he added 10.35+7.6

Step-by-step explanation:

Steps to add decimals:

1)Write down the numbers, one under the other, with the decimal points lined up

2) Put in zeros so the numbers have the same length

3) Then add using column addition, remembering to put the decimal point in the answer

Applying the above steps:

line the decimals up             10.35

                                                7.6

Putting zero to get same length

                                              10.35

                                                7.60

Addition:

                                               10.35

                                               +7.60

                                           ......................

                                               17.95

Now we can see that, there is error when he added 10.35 + 7.6
