In a parallelogram, consecutive angles are supplementary.
3y + 78 = 180
3y = 102
y = 34
0.3333333333... = 1/3
You can just say 0.3 repeating to say 0.33333...
25
If 15 is 60% of a number, it is 3/5 of the whole. Since 5 goes into 25 5 times, and 5 goes into 15 3 times, 15 is the 3/5 of 25.
0.4/0.3=1.3
1.3 is the answer
You have to divide 4/10 and 1/3 and what ever two answers you get from there is the two that you divide
