Ok, and I have another question

Answer 17

When you do order of operations in math, you first do parenthesis (but we don't have any here so..) then you deal with the multiplication and division, then the subtraction and addition. That also means that you undo those operations first. Which is why we got rid of the 5 in the denominator first.

What is your other question?

Answer 19

Joby's plant was 6 1/3 inches tall. Pat's was 4 1/2 inches tall.



How much taller was Joby's plant than Pat's?

Answer 20

Subtract pat's plant height from jody's plant height. Get them into improper fractions and then find the common denominator. Like this, one thing at a time...
