Question

А]Вырази в дециметрах 1\2м.1\10м. б]Вырази в сантиметрах 1\5м.1\10м.Задача ]Андрей выполнял домашнее задания по математике .На решения примеров у него ушло четверть часа а на решения задачи -10минут .Сколько времени Андрей делал домашнюю работу по математике

Answer 1

А) 2 м = 20 дм, 10 м = 100 дм ,т.к  1 м = 10дм
б) 5 м = 500 см, 10м = 1000 см, т.к 1 м = 100 см
задача
в 1 час = 60 мин, значит 60 / 4 = 15 минут Андрей решал примеры
15 + 10 = 25 минут Андрей делал домашнюю работу

Answer 2

Converting Measurements:

a) To express 1/2 meter and 1/10 meter in decimeters: - 1/2 meter = 50 decimeters [[1]] - 1/10 meter = 10 decimeters [[2]]

b) To express 1/5 meter and 1/10 meter in centimeters: - 1/5 meter = 20 centimeters [[3]] - 1/10 meter = 10 centimeters [[2]]

Time Spent on Homework:

Andrey spent a quarter of an hour (15 minutes) on solving examples and 10 minutes on solving a problem in mathematics. We need to calculate the total time Andrey spent on his homework.

To calculate the total time, we add the time spent on solving examples and the time spent on solving the problem: - Time spent on examples: 15 minutes - Time spent on the problem: 10 minutes

To find the total time, we add these two values: - Total time spent on homework = 15 minutes + 10 minutes = 25 minutes

Therefore, Andrey spent 25 minutes on his mathematics homework.
