Question

There are 128 Year 7 students. Three quarters of them own a pet. A survey shows that 37 students have cats, 1/3 of the students who own a pet have dogs and the remaining students have horses. How many have horses?​

Answer 1

Hmmm, I think it’s 17. Three quarters of 128 is 96. 96 minus 37 is 59. And then 1/3 of 96 is 32, so 59 minus 32 is 17. Then there remains 17 students! So 17 students have horses. I hope this helped!
