252 you multiply the 42 and 12 then devoid even by 2
It does not make sense, because 4 is not a prime number. If it would have been 2*2*11 then it would have been correct.
1. Find the total number of class members
9 + 11 = 20
2. Find 9 as a percentage of 20
9 / 20 = 0.45
0.45 x 100 = 45%
<u>45% of the class are girls.</u>
the answer would be 7. 9x7=63. there isnt much work needed for this
