Question

У моей мамы в этом году день рождения в воскресенье.В какой день недели будет в этом году папин день рождения,если папа на 55дней младше мамы?

Answer 1

55 : 7 = 7 целых 6/7 (т.к. в 1 неделе 7 дней)

получается 7 ровных недель , а это равно 1 месяц 3 недели (т.к. в 1 месяце 4 недель). пока день недели не изменилось. 

55 - 7*7 = 55-49 = 6 дней. 

раньше вокресенья на 6 дней. воскресенье седьмой день недели. 7 - 6 = 1, а первый - это понедельник. значит день рождение папы будет в понедельник

 

Answer 2

Если бы папа был моложе мамы на 7*8=56 дней, то у него день рождения был бы то же в воскресенье. Поскольку он моложе только на 55 дней, то днь рождения придется на день позже, т.е. в понедельник.

Answer 3

Calculation of the Day of the Week for Dad's Birthday

To determine the day of the week for your dad's birthday, we need to consider the following information:

- Your mom's birthday is on a Sunday this year. - Your dad is 55 days younger than your mom.

To calculate the day of the week for your dad's birthday, we can use the fact that there are 7 days in a week. We can divide the number of days between your mom's birthday and your dad's birthday by 7 and find the remainder. This remainder will tell us the number of days after Sunday your dad's birthday falls on.

Let's calculate it step by step:

1. Your mom's birthday is on a Sunday. 2. We know that there are 55 days between your mom's birthday and your dad's birthday. 3. We divide 55 by 7 to get the quotient and remainder: 55 ÷ 7 = 7 remainder 6. 4. The remainder of 6 tells us that your dad's birthday falls 6 days after Sunday.

Now, let's determine the day of the week for your dad's birthday based on the remainder of 6:

- Sunday + 1 day = Monday - Monday + 1 day = Tuesday - Tuesday + 1 day = Wednesday - Wednesday + 1 day = Thursday - Thursday + 1 day = Friday - Friday + 1 day = Saturday - Saturday + 1 day = Sunday

Therefore, your dad's birthday will fall on a Saturday this year.

Please note that this calculation assumes a standard 7-day week and does not take into account any leap years or calendar adjustments.
