Learning and understanding Mathematics, at every level, requires learner engagement. Mathematics is not a spectator sport. Sometimes traditional teaching fails to actively involve students. One way to address the problem is through the use of interactive activities and this web site provides many of those.

"Hi There. I feel obliged to question one of your answers there. Surely 9.846 rounded to one decimal place has to be 9.9. The 4 becomes a 5."

"Hi Logan. When rounding to one decimal place you only have to consider the value of the second decimal place. You can ignore the rest of the digits.
To make it clear have a look at the diagram below. You can see that 9.846 is closer to 9.8 than it is to 9.9. Therefore it makes sense to round it to 9.8.
