Hi friends
I am studing course to improve my writing and to p- IELTS exam. Therefore, I have writing homework and I ave done it but I do not know if I have a mistake or no.
could you read my topic and tell me my mistake please?

my topic is

The survey illustrates opinions ten students in Britain and the questions have been asked at the University. Firstly, about sixty percentages of students keep in touch with their friends and family twice a week. In addition, approximately twenty percentage of them keep in touch once a week. The second question was about English food and nine out of ten students do not like it while a fifth of them find it are acceptable. What is more, the vast majority of the students travel rarely for a holiday per a year, whereas a quarter of them travel twice a year. Furthermore, a fifth of students speak to English people while  a double quarter of them speak a lot to English citizens. Moreover, half of students go shopping twice a week and just under a thirty percentages of them go a lot, whereas a fifth of them go shopping rarely. All of the students have found difference between their culture and British culture.     
Eventually, although almost of the students think that living with English family are very useful, a tenth percentages think that  it is unhelpful.                                                                                                 

Hi
First when you mention a number you have to use percent not percentage eg, twenty percent
second some mistakes regarding singular and plural eg, although most of the students think that living with English family are very useful, is in place of are
Third try to use formal writing not (keep in touch )
Fourth: fifth of them find it are acceptable, there is no need for (are) here,  fifth of them find it acceptable.
any how it is a nice one keep trying just like me.
