Scientific notation is used in science because the number can be vary from so much that using decimal is making it hard. The number expressed in
form. Both number in the question is already in scientific notation. Then to multiply the number and keep it at scienfitic notation the calculation should be:
2.5 x
x 9 x 
= 22.5 x 
= 2.25x
Scientific notation is used in science because the number can be vary from so much that using decimal is making it hard. The number expressed in
2.5 x
So,
#1:
Convert to like improper fractions.
Add.
So, one solution could be
.
Another solution could by 9. There is also 10, 11, 12, etc., and all numbers in between.
#2:
Convert into improper fraction form.
Multiply.
Cross-cancel, and we have our final result.
k < 96
96 is not a solution.
95 is a solution.
So is 94, 93, 92, etc, and all numbers in between.
