Answer:
1) 4/15
cut 4 with 20, you will get 5. Cut 9 and 12 with 3, you will get 3 and 4 respectively. Now finally you will get 1/3*4/5. Now do the 3*4 you will get 15.
2) 1/16
At first make the division into multiplication, to do that you have to put 10 down that's mean you will get 1/10. Now cut the 10 with 5, you will get 2. Finally you will get now 1/8*1/10. Now do the 8*2. You will get 1/16.
3) 270/419
Take out the points of 5.4 and 8.38. Now you get 54/10*100/838. Now cut one zero of 100 and 10. And then cut 54 and 838 with 2. Finally you get 27*10/419. Now do the 27*10. You get 270/419
4) 216
3 is the power of 6. So multiple 6 three times by itself, You get 216.
5) 209.4
Take out the point of 2.094. You get 2094/1000*100. Now cut double 0 from 1000 and 100. You get 2094/10 and make the 10 point of 2094. Finally you get 209.4.
6) -132
Do the multiplication of 11 and 12, you get 132. But as "-" is there in front of 11. So you get -132.
7) 144
square means 12 will have power of 2, so multiple 12 two times by itself. You will get 144 but not -144 because you are actually doing -12*(-12), and for "-" and "-" you get "+".
