38/6 = 19/3
divide 19 by 3 :-
= 6.333....
The 3 is recurring
All you have to do is divide the ounces he has into how much he gives the dog each day so 128/8 is 16
A since 19 x 29= 551 and 551/375 is around 1.5
The total 'parts' of the ratio is 10 (3+7).
Complementary angles add to 90 degrees.
Divide 90 by 10 and you get 9.
Each 'part' is 9.
3:7 * 9 = 27:63
One angle is 27 degrees and the other is 63 degrees.
A is the only equation that would reflect this table
