Rewrite each fraction as a single fraction

a) 3/8-1/6. b) 4/5+3/5. c) 5/9-1/5

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

number 3.) 16/45
