Answer:
9:28
Step-by-step explanation:
total amount of spectators = spectators who cheered + spectators who booed + spectators who were silent = 18 + 6 + 32 = 56
ratio of number of spectators who cheered (18) to total number of spectators (56) = 18:56
note that 2 is a common factor of both as both end in an even number, so both 18 and 56 can be divided by 2
18:56 = 9:28
