Answer: Her estimation is not reasonabl.fdgfdgfdgfd
Step-by-step explanation:
Since we have given that
38% of 63.
He estimated 38% as 40%
and
63 is estimated as 70.
and then he multiplied 70 by 0.4 and get 28.
But her estimation is not reasonable.
63 must be estimated as 60 instead of 70.
We always check the last digit, if is more than 5, then it is rounded off to next digit.
If the last digit is less than 5, then it is rounded off to that digit itself.
So, In case of 63, last digit is 3 which is less than 5 so, it will becomes 60.
So, 40% of 60 is given by
Hence, her estimation is not reasonable.

Given is square root of a negative real number, i.e.
When we find square root of positive real numbers, we get Real answers.
But when we find square root of negative real numbers, we get Imaginary answers. To solve them, we can split the given negative number into product of -1 and the number itself but with positive sign. e.g. -4 = -1 x 4.
For square root of -1, we use english letter 'i' called Imaginary unit i.e.
Now we can use -0.25 = -1 x 0.25
Hence, "0.5i" is the final answer.
Okay,
1. Multiply 4 x 4.
2. Then Since 4 x 4 is 16 it would be 16 over 6 (
)
3. Then Simplify, 6 can go into 16 twice, being 12.
4. There is 4 left over, so put 4 over 6 (
)
5. Finally, simplify again, 4 can be divided by 2, so can 6, make it 2 over 3 (
)
Answer: 12 and 2 over 3 (
)
