    hello the answers are:
    1,c
    because -0.231= -231/1000; -0.232=-232/1000, a,b and d are incorrect therefore it’s c
    2,b
    because 1.34+0.79+2.11+4.76=9 1/3 of 9 is 3, it’s discout so subtract 3, which gives you 6
    3,I dont really understand the question, but the first step is wrong, because 2/5 to the power of 2 is not 4/10(but if it is 5° -4/10° then it’s correct), so second step would be wrong too, but I don’t get the 24(?).
    4,a
    because (9/11)°=9/11 times 9/11 so top number multiply by top number; buttom number multiply by bottom number, which gives you 9 times 9=81; 11 times 11=121
