16a.) π
16b.) 
= 7 ÷ 15
Put (7 ÷ 15) in your calculater to get 0.4666667
That multiplied by 100 and rounded to the nearest whole percent is
47%
17a.) 24 + 16 + 14 = 54
17b.) 8 ÷ 27 = 0.296
0.296 × 100 = 29.6
Rounded to the nearest whole number is 27%
Common ratio = 28/7 = 4
8th term = (first term)4^7 = 114688
I’m pretty sure it’s 240 because you multiply then add
