Many children never master fractions. When asked whether 12/13 + 7/8 was closest to 1, 2, 19, or 21, only 24% of a nationally representative sample of more than 20,000 US 8th graders answered ...

On his website andertoons.com, illustrator Mark Anderson has a cartoon in which a boy is handing his teacher an assignment. “To show how well I understand fractions,” he says, “I only did half of my ...

For instance, \(\frac{2}{9} + \frac{3}{9} = \frac{5}{9}\) or \(\frac{6}{11} - \frac{4}{11} = \frac{2}{11}\). Work out \(\frac{4}{7} + \frac{1}{3}\). Create a common ...

Save guides, add subjects and pick up where you left off with your BBC account. Work out \(\frac{4}{7} + \frac{1}{3}\). Create a common denominator by looking for the lowest common multiple of 7 and 3 ...

A year after he started his Ph.D. in mathematics at McGill University, Matt Bowen had a problem. “I took my qualifying exams and did absolutely horribly on them,” he said. Bowen was sure that his ...

Recent research showed that cross-notation magnitude knowledge of fractions and decimals was related to better performance in fraction arithmetic, but it remains unclear whether it made an independent ...
