Answer:
undefined
Step-by-step explanation:
First you must change 3/8 into a decimal, so the number would be 45.375. To find scientific notation you have to move the decimal between a factor of 1-10. 4.5375 . You moved over the decimal once toward the left. so scientific notation would be 4.5375 X 10^1
19/2 = 19 divided by 2 = 9.5
