Jack and Jill use rain gauges the same size and shape to measure rain on the top of a hill. Jack uses a rain gauge marked in fourths of an inch. Jill's gauge measures rain in eighths of an inch. On Thursday, Jack's gauge measures 2/4 inches of rain. They both had the same amount of water, so what was the reading on Jill's gauge Thursday? Draw a number line to show and explain your thinking.

By rewriting the fraction, we will see that Jill's measure will be 4/8 in, or 4 eights of an inch.

What was Jill's measure that Thursday?

We know that:

  • Jill's gauge measures on eights of an inch.
  • Jill's measure must be equivalent to the jack one (because they did it on the same day).

Jack's measure is;

m = 2/4 in

We want to just rewrite this in such a way that it is expressed in eights of an inch instead of fourths, to do that, we can multiply and divide by 2 (this is equivalent to multiply by 1, so it does not change the actual value).

m' = (2/2)*( 2/4 in) = 4/8 in

That would be Jill's measure.
