Hi!

To get a good estimate you would round 47% up to 50% and 89 up to 90. Since 50% is half, making one of your answers divide 90 by 2.

You can also round 47% to 50% and make it into a decimal, so .5. This means you can also multiply .5 by 90.

Lastly, you can round 47% to 50% and make it a fraction, which would be 1/2. Therefore, you can multiple 1/2 by 90 and get the same answer.

Overall, the correct answers should be A, B, and D.

Hope this helps!

Hey there! :D

Remember that the question said estimate.

So

47% rounds to 50%

.5 and 1/2 are equal to 50%

89 rounds to 90.

You could say that:

1/2*90

0.5*90

90/2

These will all work and will give you the same answer.

I hope this helps!
