Let's solve a math problem: what number is halfway between 1/3 and 1/2? We find a common denominator (6), then calculate the distance (1/6). Half of that distance is 1/12. Adding 1/12 to 1/3 gives us 5/12. #MathExplained #Fractions #ProblemSolving #MathTips

Comparing fractions close to one: 11/14 and 10/13. Both are 3 away from a whole. Since 11/14 is missing smaller pieces, it's the larger fraction. Dividing a larger number by a smaller number results in a value greater than one. #MathTips #FractionComparison #LearningMath #MathExplained
