1/2 of the children at a party like chocolate ice cream, 2/3 like vanilla ice cream, and 1/3 like chocolate and vanilla. What fr

alexandr402 [8]

Answer:

$\frac{1}{2}$

Step-by-step explanation:

We have been given that 1/2 of the children at a party like chocolate ice cream, 2/3 like vanilla ice cream, and 1/3 like chocolate and vanilla.

To find the fraction of children, who like vanilla also like chocolate, We will divide the fraction of children who like chocolate and vanilla by the fraction of children who like vanilla.

$\text{Fraction of those who like vanilla also like chocolate}=\frac{\frac{1}{3}}{\frac{2}{3}}$

Since we know that dividing a fraction by another fraction is same as multiplying the first fraction by the reciprocal of second fraction.

$\text{Fraction of those who like vanilla also like chocolate}=\frac{1}{3}\times\frac{3}{2}$

After cancelling out 3 from numerator and denominator of our fraction, we will get,

$\text{Fraction of those who like vanilla also like chocolate}=\frac{1}{2}$

Therefore, the fraction of those who like vanilla also like chocolate is $\frac{1}{2}$ .

It took everly 55 minutes to run a 10-kilometer race late weekend. If you know that 1 kilometer equals 0.621 miles, how many min

Ket [755]

Well this type of problems isn't exactly my strong suit, but I tried to come up with a solution, so my reasoning is as follows: we know that 1km is 0.621 miles, and the problem incites us to find how much time 1 mile takes, so we need to find how many kms are in a mile:
1km ---> 0.621 miles
<=> 1/0.621=1.610 km ---> 0.621/0.621 = 1 mile
so 1 mile = 1.610 km
Next we need to know how much time 1.610 km takes to run across
We know that:
10 km take 55 mins
and 1.610 = 10/6.211
so we need to divide 55 by the same value
55/6.211 = 8.855 mins
So 10 km ---> 55 mins
1.610 = 10/6.211 km ---> 55/6.211 = 8.855 mins

I hope I didn't mess up.
Hope I helped ^^
