GOOD MORNING BOYS:

Hope you have done the first five word problems of Exercise 3.3 in your copy. Today, let us continue the exercise doing the questions 6, 9 & 10.

CONCEPT:
To find the value of "many", we need to multiply the value of "one" with the given number.

Please open your text book, turn to page number 41 and underline the following in the questions 6, 9 & 10. Are you ready?  Here we go...
6) ...a page...
9)...a bundle...
10)....a mathematics text book....

You will find  that value of "one" is given and value of "many" is asked. Hence, we should multiply.
This means,"One to Many multiply".  Got it!!!
Now let us do the sums:

6) How many words are there in the whole book of 372 pages, if there are about 452 words on a page?
No. of words on 1 page       =                452
No. of words on 372 pages =                452 x 372
Answer                               =                 452
                                                               x 372
                                                               -----------
                                                                 904
                                                             31640
                                                           135600
                                                          ------------------
                                                           168144 words
                                                          ------------------

9) A flower exporter packs 628 roses in a bundle.  How many roses are there in 536 such bundles?
No. of roses in 1 bundle                =    628
No of roses in 536 bundles            =    628 x 536
                                                              628
                                                              x536
                                                            ------------
                                                               3768
                                                             18840
                                                           314000
                                                        ------------------
         Answer:                                     336608 roses
                                                        ------------------

10) There are 256 pages in a mathematics textbook.  How many pages are there in 2186 books?
No. of pages in 1 text book            =      256
No. of pages in 2186 books           =      2186 x 256
                                                                2186
                                                                x256
                                                                ----------
                                                                4372
                                                            109300
                                                            437200
                                                           -----------------
Answer:                                              559616 pages
                                                           -----------------
