number 1.)
Step 1: Find the least common denominators (LCN) in your case it's 24
Step 2: Multiplying numerators and denominators to get the LCD in all fraction denominators yours looks like this: 3x3/8x3-1x4/6x4
Step 3: Rewrite the fraction with the equivalent fraction: 9/24-4/24
Step 4: With denominators we can just subtract the numerators 9-4/24
anwser= 5/24
number 2.) 1 and 2/5
