Answer: OPTION D.
Step-by-step explanation:
You have the expressions given in the problem:
To find the product of both expression you must multiplicate them.
You must multiply the numerators of both expression and the denominators of both expression.
Keeping the above on mind, you obtain that the product is:
30%*470=141 (So the number of students in 8 grade is 141)
So Scientific Notation is a "simplified version" of a number. For example, is your number is 2,345, the scientific notation would be 2.345 * 10³.
If it was 0.023, then the scientific notation would be 2.3 * 10^-2.
Scientific notation is found by moving the decimal place to the left or right, until only one digit is left to the left of the decimal; it has to be greater than 1, but less than ten. If you move the decimal place to the right, it's a negative power of 10. If you move it to the left, it is a positive power of 10.
Hope this helps!
