To round that number to the nearest tenth, which is the seven, you would need to either round the six up or down.
If you round up, the number you rounded was 5 or over.
If you round down, the number you rounded what under 5.
So, in this case, you would round the 7 up to an 8, because the 6 causes it to be rounded up.
The answer is 9.8
