In the bakery 1⁄3 of the cakes have strawberry frosting and 3⁄7 of the cakes with strawberry frosting have vanilla filling. What fraction of the cakes at the bakery have both strawberry frosting and vanilla filling?

Step-by-step explanation:

Let the number of cakes in the bakery be x.

Given:

Fraction of cakes with strawberry frosting = 1/3 of x

Fraction of cakes with strawberry frosting that have vanilla frosting = 3/7

Fraction of cakes with strawberry frosting with vanilla frosting in the bakery = 1/3 × 3/7 × x

= 1/7 x

fraction of the cakes at the bakery have both strawberry frosting and vanilla filling = 1/7

step-by-step explanation: a reaction is first order. if the initial reactant concentration is 0.0200 m, and 25.0 days later the concentration is 6.25 x 10-4 m, then its half-life is:
