How to solve difficult fraction comparison problems in a few steps

thumb_how-to-solve-difficult-fraction-comparison-problems-in-a-few-steps

Comparison of fractions is a tricky process, but if you learn to use patterns inherent in a set of fractions, you should be able to quickly solve even knotty fraction comparisons by applying a suitable method exploiting the pattern. In this session, as many as six different techniques of fraction comparison are presented with examples...

How to solve Clock problems

thumb_how-to-solve-clock-problems

In an analog clock the minutes hand moves faster than the hour hand and crosses it 22 times in a day, both going round and round over the clock face. In a typical clock problem, we are asked to find the angle between the two clock hands at a specific time...

How to solve difficult Time and Work problems in simpler steps, type 3

thumb_How-to-solve-difficult-time-work-problems-in-simpler-steps-type3

In a large number of math problems involving Time and Work, when more than one group of workers each comprising of a certain number of members, complete a job taking their own time, and the question is to find time taken by similar groups of workers but with different number of members, worker equivalence method invariably leads to much faster conceptual solution with greatly reduced calculation load...
