120 pupils went on a feildtrip . 55% of the pupils were girls and the rest were boys. How many boys went on the trip?

54 boys went in the trip

Step-by-step explanation:

55% of 120 is 66 and 66 minus 120 is 55

1. is 4 and 2. is 3

step-by-step explanation:

so if you look at the first one you see that 1 is to 4 and 2 is to 8 and so on, so you can see for every 1 there is a times 4 so if it were 3 then it would be 3*4 and it is 12

for number 2 it is 3 because 1 is to 3 and 2 is to 6 so for every 1 there is 3 so if it were 3 then there would be 3*3 = 9
