Step-by-step explanation:

We can write a proportion to solve

14         10

------ = ------

21          x

Using cross products

14x = 21*10

14x =210

Divide each side by 14

14x/14 = 210/14

x =15

Answer 2

The answer is easily 15 as 21/14 is 1.5 then you multiply 1.5 tines 10 which gives you 15.Hopefully this helps.
