(36 and 1/2) - (29 and 1/4)
= (36 and 2/4) - (29 and 1/4)
= (7 and 1/4)
[(7 and 1/4) / (36 and 1/2)] * 100%
= [(29 / 4) / (73 / 2)] * 100%
= [(29 * 2) / (4 * 73)] * 100%
= (58 / 292) * 100%
= (29 / 146) * 100%
= 19 and 63/73 %
Hence, from (36 and 1/2) to (29 and 1/4), there is a (19 and 63/73) % decrease.
