Answer:
4 quarters
10 tenths
Step-by-step explanation:
<h3>Tenths</h3>
<h3>Quarter</h3>
<h3>Whole</h3>
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

∴ There are <u>4</u><u> </u><u>quarters</u> to make a whole
∴ There are <u>10</u><u> </u><u>tenths</u><u> </u>to make a whole
You have to make them have their least common denominator to add or subtract, in this case 36.
Multiply 1/12 by 3, to get the denominator 36: 3/36.
Multiply 7/9 by 4, to get the denominator 36: 28/36.
Now add the numerators: 3+28=31, 31/36 is as simplified as possible so your answer is 31/36 :) I hope this helps :)
Dy/dx = dy/dt / dx/dt
dy/dx = 12x^2 + 4
when x = 2 , dydx = 52
52 = dy/dt / 3
so dy/dt = 156 (answer)
Answer:
16 questions right = 80%
So Peter missed 4 questions.
Hope this helps.
