Question

Sandra has 24/5 pounds of flour. Tina brought 23/6 pounds of flour. Sandra estimates that she has more than Tina. is she correct? How could you solve this?

Answer 1

One of the better ways of addressing this is to convert both fractions to incorporate the LCD. The LCD here is 5(6) = 30, so

24/5 = 144/30 and 23/6 = 115/30. Obviously 144/30 is greater than 115/30,

so 24/5 is greater than 23/6.

Alternatively, find the decimal equivalents to 24/5 and 23/6 and then compare the results.
