Answer:
We need approximately 1667 floppy disc to store bytes of data.
Step-by-step explanation:
We are given the following information in the question:
A floppy disc can store 1440000 bytes of data.
We have to convert 1440000 in a standard form.
Standard Form:
- Standard form is a way of writing down very large or very small numbers easily.
- It helps us to express large numbers in powers of 10
The standard form can be written as:
We have positive power of 10 because we have to move to the right of the decimal point.
A hard disc can store bytes of data.
Number of floppy disks needed to store the bytes of data =
Thus, we need approximately 1667 floppy disc to store bytes of data.
Answer:
6
Step-by-step explanation:
First you add the whole numbers 1 + 4 which will be 5
Then you add the fractions. To do that you have to make sure that the denominators are the same (in this case they are not). So you multiply the fraction by a number so the denominators can equal each other.
1 (4) /2 (4) + 3 (2) / 4 (2)
+
=
= 1
= 1
*always remember to simplify the fractions
After adding the fractions, you just have to add it to the whole number (5)
5 + 1 = 6
hope this helps!
