Hello there!

Standard form is used for large or small numbers. It is between 1 and 10 times 10 to the power of something.
In this case, your answer is 1.8 x $10^{-1}$ .

Hope This Helps You!
Good Luck :)

3 1/2 - 4 2/5<br> how do i do this?

Answer:

Ok so first you would have to turn them into improper fractions which is

3 $\frac{1}{2\\}$ = $\frac{7}{2}$ and 4 $\frac{2}{5}$ = $\frac{22}{5}$

So now that you have made them both improper fractions you have to find common denominators.

To find common denominators you must multiply both the numerator and the denominator by the same thing. Since your oposing fraction has a denominator of 5 you can know that a even number wont go in an odd number so take $\frac{22}{5}$ and mutiply both numbers by 2 and get $\frac{44}{10}$ . Then mutiply both numbers in $\frac{7}{2}$ by 5 to get a common denominator.
