Answer: Part A: 44/30 or 1 and 7/15. Part B: 17/30
Step-by-step explanation: Convert all the fractions to a denominator of 30 and do the adding and subtracting.
Ok so..
there are a total of 30 socks.
100% would be 30 socks
50% would be 15 socks and
10% would be 3 socks
so the 50% + 10% = 60%
60% - 18 socks
40% - 12 socks
common ratio - 18:12
simplified: 3:2
There is a greater possibility of getting red socks by 3/2 (also 1 1/2)
But I'm kinda stuck between A. and C.
Help anyone?
