Answer:
x = 20
Step-by-step explanation:
Write and solve an equation of ratios, as follows:
1 3/4 14
------------ = --------
2 1/2 x
where x is the unknown number.
Converting the mixed numbers to improper fractions, we get:
7/4 14
------ = -----
5/2 x
Here there are two numerators and two denominators. Multiplying all four quantities by 4 will remove some of the fractions:
7 56
------ = -------
10 4x
Cross multiplying, we get:
28 x = 560, or x = 20
