8/25 х=3 1/5
Представим дробь справа как неправильную: 3 1/5= (15+1)/5=16/5
Приведём дроби справа и слева к общему знаменателю:
16/5=80/25
Имеем уравнение:
8/25х=80/25
Умножим уравнение на 25:
8х=80

Meet Adeliya. She's a grade 6 student at Panfilov Kazakhstani-Russian Gymnasium, 54 in Almaty. It's a big school with about 1,500 students. During term time, Adeliya usually follows the same routine. Her day starts early. She usually gets up at 7 o'clock. Then she has a shower. Then she gets dressed and goes downstairs for breakfast. After breakfast, she finds the things she needs for school. When she's ready, her grandma, Raissa, takes her to school on foot. Adeliya usually has six lessons a day. Her favourite lesson is Kazakh, but she doesn't like P.E. At 11 a.m. there is a break, and Adeliya has brunch with her classmates. They usually have buns with tea or apple juice. When school finishes at 2 p.m., her grandma meets her and they go back home. They have lunch together and talk about their days. They usually have meatballs with mashed potatoes or chicken soup, because they are Adeliya's favourite foods. Adeliya is a very hard-working student, so in the afternoon she always does her homework and gets ready for the next day. Three days a week, Adeliya goes to a music school. She's in the choir and they practise singing and learn new songs. In the evening, she usually goes for a walk with her friends and her brother Dias. Adeliya is busy, but if she has time she helps her mother around the house. At 10 p.m. Adeliya goes to bed.
