Answer:
NEVER MIND A IS CORRECT
Step-by-step explanation:
160 of 72 % is 115.2
but in total it is of 222.2
18
we start to write a few iterations of 6 and 9:
6, 12, 18, 24, 30, 36, 42, 48, 54, 60, ...
9, 18, 27, 36, 45, 54, 63, 72, 81, 90, ...
the LCD is the least repeating number in both sequences. It is 18
a= 3/11
b = 2/11
a(1) + b(4) = 1
a + 4b = 1
a(3) + b(1) = 1
3a + b = 1
b = 1-3a
a + 4(1-3a) = 1
a+ 4-12a = 1
-11a = -3
a = 3/11
b = 1-3(3/11)
b= 2/11
