Interquartile range is the range is the number in the dead center, you have to divide the number line into 2 sections. The middle of everything and the middle of both section is the interquartile range
To get rid of the 2/5 next to the g, multiply both sides by the RECIPROCAL of 2/5, which would be 5/2. The answer is g=15/10, which simplifies to g=1 5/10 and then further simplifies (wow so much simplifying) to get g=1 1/2.
