The first question, 8 out of 8 15 and 8 out of 3 out of 8 are omitted, leaving 3 out of 15, that is, 1 out of 5, and 5 out of 9 omitting this 5, and the final result is one out of 9.

The second question, 22 and 1 1 are about 27 14, 14 and 14 are about 27 9, that is, 3 1.

The third question, 2 and 2 are rounded, which is 3/7, and then 14 is rounded, which is 2 times 3, and the result is 6.

The fourth question, the denominator is 3, and the numerator is 3, which is 1, and then multiplied by 8 is 2.

The fifth question, 7 and 2 1 about one-third, 12 and 8 about one-third, one-third times one-third equals nine-tenths, and nine plus nine is about one-third. The result is 1 in 10.

The sixth question, 5/6 times 3/5, 5 plus 5 loses about 3/6, that is, 2 times 4 1 equals 2.
