Answer:
Step-by-step explanation:
9+7+2=18
But since there are only 12 people in the class, its overlapping. So 18-2(the people that have nether), is 16.
So 16-12 is 4. Therefore 4 people have both a brother and a sister.

It is easy for me!
5/17 - Rational (R)
8.07 - R
4
= I
0.<u>5555555555555555</u>... = I
0.5 with a bar over 5 means that the 5's recur (look above. I have underlined it for you).
22 - R
If you see the "..." that means that a number is 100% irrational.
-5.217408...
The square root of 49 is 7. R
0.18 R
√18 = I
6+1/5 = R
10.613902... I
√36 - R
2.462 (with 462 recurring) I
-12π - I
-6, 302, 015 - R
5.4735 - R
√2 = I
-13.03003... I
-2/3 - R
10.056 (with 6 recurring) = I
Good luck with Maths! I hope my answer was helpful!
