Answer:

14.3€

Step-by-step explanation:

Let:

C=Price\hspace{3}of\hspace{3}the\hspace{3}shirt\\P=Price\hspace{3}of\hspace{3}the\hspace{3}pants\\T=Total\hspace{3}cost

Now, let's write the data provided by the problem, using algebraic notation.

The total cost of the clothes is 20€, so:

P+C=T\\\\P+C=20

The price of the shirt is :

C=\frac{2}{5} P

Replacing this value into the first equation:

P+\frac{2}{5} P=20

Solving for P:

\frac{7}{5} P=20\\\\P=\frac{100}{7} \approx 14.3

So, the price of the pants is 14.3€ and the price of the shirt is:

C+14.3=20\\\\C=20-14.3=5.7

Translation:

Deja que:

C=Precio\hspace{3}de\hspace{3}la\hspace{3}camisa\\P=Precio\hspace{3}del\hspace{3}pantalon\\T=Costo\hspace{3}total

Ahora, escribamos los datos proporcionados por el problema, usando notación algebraica.

El costo total de la ropa es de 20 €, entonces:

P+C=T\\\\P+C=20

El precio de la camisa es:

C=\frac{2}{5} P

Reemplazando este valor en la primera ecuación:

P+\frac{2}{5} P=20

Resolviendo para P:

\frac{7}{5} P=20\\\\P=\frac{100}{7} \approx 14.3

Entonces, el precio del pantalón es de 14.3 € y el precio de la camisa es:

C+14.3=20\\\\C=20-14.3=5.7

What's the next fraction after 45/60
Darya [45]
You could say 46/60 (both of these fractions can be reduced), but we can find a fraction between 45/60 and 46/60, namely 91/120.  And we can find another between 45/60 and 91/120, and so on ad infinitum.

To answer your question, there is no next fraction.  Infinitely many may be found between any two.
