Tell and Set Time to the Nearest Quarter Hour

In this chapter you will learn to tell time quarter past and quarter to and time to half hour. Constructing on this, tell time quarter hour problem in maths focuses on telling time to quarter hour, using both digital and analog formats. The time quarter past and quarter to math problems consists of interactive problems on reading time on a clock, setting time on an analog clock, and exposes students to different ways of saying the same time. For example, 3:45 and quarter to 4 are different ways of saying the same time.

Time Quarter Past, Quarter to and Half Hour

Let’s get to know the various ways to tell time to quarter hours

• In 5 minute augmentations, when it's past the hour (up to 30 minutes past) we say "past".

• When it's before the hour (after 30 minutes past) we state "to".

• There are 60 minutes in an hour.

• 30 minutes is half an hour (exactly half of an hour/half of 60 minutes), we say "thirty" or "half past".

• Fifteen minutes is quarter of an hour, we say "quarter past" or "quarter to" or "fifteen" or "forty-five".

• 09:00- it’s nine o'clock in the morning.

• 15:00- it’s three o'clock in the afternoon.

• 15 minutes past the hour is said to be quarter past: 

• 06:15- it’s quarter past seven in the morning (6:15 is 6:15 AM in the morning)

• 13:15- It's quarter past two in the afternoon. (13:15 is 1:15PM in the afternoon)

Time Measurement to Tell Time to Quarter Hours

Time measurement for 15 minutes, 30 minutes, and 45 minutes can be depicted in the following manner. They are:

1. Quarter to - This implies that there are 15 minutes remaining to complete a given hour. For example, 06:45 means there are 15 minutes still remaining to reach 7:00. This is also read as "quarter to seven".

2. Quarter Past - This implies that 15 minutes have passed after the hour has begun. For example, 09:15 means 15 minutes have passed after 9:00. This is read as "quarter past nine".

3. Half-Past - This implies that 30 minutes have passed after the hour has begun. For example, 06:30 means 30 minutes have passed after 6:00. This is also read as "half-past six".

Solved Examples

Let’s practice some quarter hour problem in maths that you will find in your tell time quarter past and quarter to worksheets.

Example:

Calculate the measurement of time between 1:00 to 5:00.

Solution:

The distance between two vertical lines depicts 1 hour. Thus, there are 4 hours between 1:00 and 5:00.

Therefore, the time between 1:00 and 4:00 is 4 hours.

Example:

Alex's and Amaira anniversary falls on June 9. Their friend's anniversary falls on September 17. Find out the number of weeks and days between the two dates.

Solution:

The month of June consists of 30 days. The number of days after Alex's and Amaira anniversary (June 9) is 30 - 9 = 21.

The Months of July and August have 31 days each. Beginning from 1st to 17th, we have 17 days in the month of September. So, there are (21 +31+31+17) days which equals 100 days.

In order to find the number of weeks, divide the number of days by 7 and express the outcome as a mixed fraction. 100/7 is 14 2/7 weeks.

∴ There are 102 days between Alex's-Amaira’s and their friend's anniversary.
