Between two given rational numbers, we can find
- (a)one and only one rational number.
- (b)only two rational numbers.
- (c)only ten rational numbers.
- (d)infinitely many rational numbers. Plan a strategy • Some problems contain a lot of information. Read the entire problem carefully to be sure you understand all the facts. You may need to read it over several times, perhaps aloud so that you can hear yourself and understand it well. • Then decide which information is most important (prioritise). Is there any information that is absolutely necessary to solve the problem? This information is most important. • Finally, put the information in order (sequence). Use comparison words like before, after, longer, shorter, and so on to help you. Write down the sequence before you try to solve the problem. Read the problem given below, and then answer the questions that follow • Five friends are standing in line for the opening of a show. They are in line according to their arrival. Shreya arrived 3 minutes after Sachin. Roy took his place in line at 9:01 P.M. He was 1 minute behind Reena and 7 minutes ahead of Shreya. The first person arrived at 9:00 P.M. Babu showed up 6 minutes after the first person. List the time of each person’s arrival. (a) Whose arrival information helped you determine each person’s arrival time? (b) Can you determine the order without the time? (c) List the friends’ order of arrival from the earliest to the last. x +y
