Bernie’s estimated that 69% of 242 is 168 is her estimate reasonable

Yes it is.

Step-by-step explanation:

Best way is to use percentages you know when estimating.

We know 50% is half.

50% of 242 is 121.

So it has to be more than 121.

10% of 242 is 24.2  so add that to 121 and you get 145.2

You are 60% so far. You just need 9% more.

Add another 10% which is 24.2 and you get 169.4, which is over but we used 10% instead of 9% so the estimate is reasonable and close.
