31.5% of 473 can be calculated as follows
(31.5/100) * 473
= 14899.5/100
= 148.99
hope it helped
7(x+1)=63
7 times a number(x) +1
1. 1/9 since you take all the "a"s in the words which is 2/18
2.2/9 same thing as above
3.18/18 since there is no "O" it's a trick question
4.3/9
5.5/6 since you don't count 6
6.1/2 and 1/2 coins are always 1/2 unless you flip twice
7.5/13
8.1/2 because 1,3,5 odd 2,4,6 even
Hope that helps
