Please choose the correct ending to complete the given sentence: Education and Communications: [header] How to multiply fractions [title] Write out the problem. [step] The two fractions should be written down so that their numerators are aligned with their denominators. [substeps] Ex : 2/4 * 2/4 [title] Multiply the numerators of the two fractions.

Ending1: [substeps] Ex : 2/4 * 3/4 + 1 = 44 [title] Divide the two fractions. [step] The simple addition of the numerator and denominator gives the fraction 34. Ending2: [step] There should be a sum of the denominators of both fractions equal to 2. A formula to start is : [substeps] 1/(1/1=1/2), (2/1=1 , 2/1=2). Ending3: [step] The numerators of the two fractions should follow the same sequence of denominators. [title] Divide the numerators of both fractions by the denominators of both fractions. Ending4: [step] Since the numerators are both 2, you can multiply 2 * 2 to get 4. [title] Multiply the denominators of the two fractions.
