Fracciones equivalentes

Dos fracciones son equivalentes cuando represntan la misma cantidad, aunque los numeradores y denominadores sean diferentes.

y

son fracciones equivalentes

Para comprobar si dos fracciones son equivalentes, puedes usar la siguiente propiedad:

$\frac{a}{b}$ y $\frac{c}{d}$ son equivalent fractions si $\fs2a\;\text\;x\;d\;=\;b\;\text\;x\;c$ .

Para simbolizar dos fracciones equivalentes, escribimos: $\frac{a}{b}=\frac{c}{d}$

Comprueba si las fracciones $\fs2\frac{3}{5}\;y\;\frac{12}{20}$ son equivalentes:

$\fs2\frac{3}{5}=\frac{12}{20}\;\Rightarrow\;3\;\text\;x\;20\;=\;5\;\text\;x\;12\;\Rightarrow\;60=60$

por lo que ambas fracciones sí son equivalentes.

Encuentra el valor de x para que estas fracciones sean equivalentes:

$\frac{20}{20}=\frac{x}{8}$

Solución x=
