Points to remember: Time 1. Converting 12hr clock to 24 hr clock For a.m. no change and write hrs using 4 digits except for 12 in hrs place. 12 in hrs place becomes 00. Ex: 9:30 a.m. 0930hrs. 12:45 a.m. 0045hrs For p.m. Add 12 to the hrs place and write with hrs except for 12. 12 in hrs place remains same. Ex; 4:30 p.m. 16:30 hrs (4+12) 12:15p.m. 12:15hrs 2. Converting 24 hr clock to 12hr clock a) If number in hrs place is less than 12, write the same using a.m. b) If number in hrs place is 12 or more than 12 we use p.m. Subtract 12 from hrs place if the number is more than 12. c) 00 in hrs place turns to 12 a.m. Ex: 1) 0450 4:50 a.m. Time conversions Time interval: 2) 0020 12:20 a.m. 3) 1545 3:45 p.m. (15-12) 4) 1228 12:28p.m. 1 day = 24 hrs 1 hr = 60 min 1 min = 60 sec.

Convert into: a) Hours: i) 7days ii) 4days 15hrs iii) 9days 20 hrs b) Minutes: i) 16 hrs ii) 13hrs 35min iii) 15hrs 20min c) Seconds: i) 12min ii)7min 36sec iii) 40min 56sec. 59. Addition and subtraction of time: 1) 14 hours 42 minutes + 3 hours 18 minutes 2) 9 hours 25 minutes + 2 hours 52 minutes 3) 12 hours 17 minutes + 1 hour 59 minutes 4) 8 hours 29 minutes + 12 hours 34 minutes 5) 11 hours 25 minutes + 7 hours 59 minutes 6) 11 hours 39 minutes - 8 hours 26 minutes 7) 9 hours 25 minutes - 2 hours 52 minutes 8) 16 hours 17 minutes - 3 hours 29 minutes 9) 13 hours 38 minutes - 1 hour 37 minutes 10) 5 hours 22 minutes - 3 hours 39 minutes
60. Find the time interval Fraction 1. A is a part of a whole 2. The number above the fractional bar is called 3. The number below the fractional bar is called 4. quarters are there in a whole 5. halves make a whole 6. quarters are there in one half 7. quarters are there in three- fourths 8. Three quarters can be represented as 9. In 8/15, numerator is and denominator is 10. Fractions which indicate the same value are fractions 11. Fractions that have the same denominator are called fractions 12. Fractions that have the different denominator are called fractions 13. Compare 9/16 10/16 14. A fraction with the numerator less than the denominator is a fraction 15. A fraction with the numerator greater than or equal to the denominator is a fraction 16. Proper fractions that have one as the numerator are called fraction 17. Fractions having a whole number and proper fraction are called fractions 18. ½,1/9, 1/4., 1/8 are called fractions 19. 17/8, 11/8, 9/8, 16/8 are fractions 20. 1/11, 4/11, 5/11, 8/11 are fractions 21.
