Answer:
Option A
Step-by-step explanation:
multiply 2/7 and 3/4
you get 6/28
then simplify
you get 3/14
72 is the answer
21-4 IS 17, AND 17 - 9 IS 8, THEN 9X8 IS 72.
the answer is
x = 40/3
it was right but ok
First find the total number
6+4+5+3 = 18
6th graders : total
4 : 18
Divide each side by 2
4/2: 18/2
2 : 9
