If the pattern shown continues, how many black keys appear on a pipe organ with a total of 120 keys? Suggestion: use equivalent ratios or a rate table to rationalize your answer. HURRY I NEEDDD HELP

in 12 key 5 black keys are appearing so consider x key will appear in 120 keys

120/x = 12/5

solving further,

x= 50

Answer - If the pattern shown continues, 50 black keys appear on a pipe organ with a total of 120 keys!

You need to find the ratio of the 120 keys so you divided instead of multiplie so the answer is 120 x 120 x 120 x 120= 120 divded by 3= 0.00833333333.  Step-by-step explanation:
