This would be D:).... C = the number of cards his brothers each get.
Divide both sides by 3.1 and find g = 20.9/3.1 ≈ 6.7 ≈ 7.
You can estimate this without a calculator by saying 20.9 ≈ 21 and 3.1≈3, then 21/3=7.
In general, be careful with rounding before a calculation, because the rounding errors can be enlarged, messing up the accuracy of your answer. It's best to round only at the end.

Answer:
B
Step-by-step explanation:
2√12 = √4 x 3 = 4√3 = (4√3 x 3√5)
√36 = 6 = (6 x √30)
4√3 x 3√5 = 12√15
6 x √30 = 6√30
12√15 x √30 180√2
÷ =
6√30 x √30 180
-----------
180√2
÷
180
------------
= √2 or 1.41
I hope this helps!
