Well that depends if his exam board rounds his percentage up, lol. 

So Bhavik needs 93% to get a level 9.

I'm going to assume that he got 89% on both his papers, (but it could be any two numbers that average to give 89%, e.g. 88% and 90%.)

Assuming that he gets 100% for his last paper (which is very unlikely), the mean value would be (89% + 89% + 100%) ÷ 3 = 92.67%.

92.67% isn't quite 93%, and it's also very unlikely for him to get 100% on his last paper (when you take the results of his last two papers in to consideration). 

So the answer is no, it's not possible for him to achieve a top grade overall. He's going to have to stick with a level 8.

What is the gcf and lcm of 60
Soloha48 [4]
The ' c ' in 'gcf' and in 'lcm' stands for 'common'. 'Common' means 'same for all of them'. There's nothing common until you have at least two things. There's no such thing as the gcf or the lcm of only one number.
