Children were asked to choose between a safari park and a zoo for the school trip.
They had a vote.
The result was a ratio of 10:3 in favour of going to a safari park.
130 children voted in favour of going to a safari park.
How many children voted in favour of going to the zoo
i need help for my test answer
10:3 = 100:30
100+30 = 130
To find out how many children voted in favor of going to the zoo, we can use the given ratio and information.
First, let's find the total number of votes by adding the two parts of the ratio:
10 + 3 = 13
Next, let's determine the "voting ratio" as a fraction, which represents the proportion of the vote in favor of going to the safari park:
10/13
To find the number of children who voted in favor of going to the zoo, we need to subtract the number of children who voted for the safari park from the total number of votes.
Since 130 children voted in favor of going to the safari park, we subtract this number from the total number of votes:
13 - 10 = 3
Therefore, 3 children voted in favor of going to the zoo.
