Answer:
The answer is 13 over 20 or 13/20
Step-by-step explanation:
Why is this the answer? Let's evaluate.
• 5 and 4 have 1 good least common multiple. This is 20. Change the denominators to 20.
• For the 2 and the 1 on top, also find the LCM least common multiple.
From there, we multiply 1/4 by 5 to get 5, and multiply 2/5 by the denominator of 1/4. Add these 2 numbers together and then simplify.
• Since 13/20 has no common multiples, and cannot be simplified, the answer is 13/20.
