![(7)/(10)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/rx7uu4995jmld2457yw4kncm86qrlnpy50.png)
To convert it in percent we need to multiply it with 100, we get
The percent of couples disagree on the matter
![=(7)/(10)*100](https://img.qammunity.org/2020/formulas/mathematics/middle-school/i5qivnyw0pge319th53ble1bqd924mw37u.png)
⇒The percent of couples disagree on the matter=70%
