Well, if you notice, is just an arithmetic sequence, is adding 2 to get the next term.
so the last term is 21, so the one before that has to be 21-2 or 19, and the one before that 17 and the one before that 15.
15+17+19+21.
Answer:
I would say 45
Step-by-step explanation:
180-90=90
90/2=45
Change the proper fraction to an improper one to do the multiplication.
3/5 x 9/7
Since this is a multiplication problem you can just multiply across.
27/35
27/35 compared to 1 2/7 or 9/7 is less than because 9/7 is greater than 1
