Ratio of odd numbers to total
First, list out the odd numbers

The card has 4 odd numbers out of a total of 6.
So, the ratio is:


Divide by 2

<em>Hence, the ratio of odd to total is 2 to 3</em>
The supplementary angle to 69 degrees would be 111 DEGREES.
because it has to add up to 180 (69 + 111 = 180)
Result, Rachel can be certain that the temperature is suitable for her cake.
1)inside the triangule is 180º .There are 3 angules, one with 120º, theta and
angle ACB, lets call it x.
x + theta + 120 = 180
x + theta= 180-120
x + theta= 60
x= 60- theta
angle ACB= 60- theta
