7 14 21 28 35 42 49 56 63 70 77 84 91 98 105 ....
If you mean 7/20 of 100 then it is 35
If you mean 7/100 then it is 0.07
In principle, you can count backwards; or use some shortcut (such as calculating the number of days, dividing by 7, and obtaining the remainder).

If you mean 7/20 of 100 then it is 35
i think there are 11
If you mean 7/100 then it is 0.07

well 9 times tables i think of like this:(Go down first column)9x1=9 9x10= 90 (09 backwards)9x2=18 9x9=81 (18 backwards)9x3=27 9x8=72 (27 backwards)9x4=36 9x7=63 (36 backwards)9x5=45 9x6=54 (45 backwards)(Now go up last column)I cant help you with 7s and 8s. But if you hav trouble just count on your handsfor example: 7 -count 7 fingers= 8,9,10,11,12,13 14 -count 7 fingers= 15,16,17,18,19,20 21 etc.You can do this with 8s as well. And im sorry if it is too slow for you. And if my 9s time table explanation is weird to understand then do the hand thing.
Sum = 42 Count = 6 Mean = Sum/Count = 42/6 = 7
Sum = 24 Count = 4 Mean = Sum/Count = 24/4 = 6
Mean = Sum/Count = 61/8 = 7.625
