Since there are 8 cookies out of 20 cookies, the probability of randomly choosing a chocolate chip cookie would be 8 out of 10, or 8/10 if you prefer fractions.
However, the fraction 8/10 can still be simplified. Divide the numerator and denominator by 2 to get 4/5.
4/5 --> 4 divided by 5 = 0.8
So the answer is 4/5 or 0.8.
What problem? i need an example or picture... sorry
Answer:
405
Step-by-step explanation:
Since
2 : 9 = 90 : X
Then we know
9/2 = X/90
Multiplying both sides by 90 cancels on the right
90 × (9/2) = (X/90) × 90
90 × (9/2) = X
Then solving for X
X = 90 × (9/2)
X = 405
Therefore
2 : 9 = 90 : 405
