Question: hi this week i have some tutorial work to do...
Hi, this week I have some tutorial work to do on ratios. I have a few questions here which I am not too sure on how to do them, one of which I have posted below. This topic is always one that is a bit hard for me to understand, so if you could, I'd prefer working out and explanation where necessary. Thank you.
On one campus ofa university there are 3rd year, 2nd year and 1st year students in the ratio of 3 : 5 : 7. If there are 306, 3rd year students how many students are there altogether and how many 1st year students are there?
