the question says, for exercises a-d decide whether the statement is correct or incorrect. Explain your reasoning in words or by drawing a picture. Please help :(

Answer:
Step-by-step explanation:
Take a. for example. Use the largest denominator and divide it by the smaller one, in this case 12 and 3. So 12/3=4. Multiple your product with the denominator. 4 x 1 = 4. Therefore 1/3 = 4/12.
Use that method for all of the questions. I hope you understand. Good luck :) !!
