gr 6 maths hcf and lcm NEED URGENT HELP!! 1. The length, breadth and height of a room are 7 m 25 cm, 9 m 25 cm and 8 m 25 cm respectively. Determine the length of the largest tape which can measure the three dimensions of the room exactly. 3. One side of a road is planted with trees 24 m apart. On the other side are lamps 32 m apart. If the first tree is opposite the first lamp, how far off is the next tree that has a lamp opposite to it? SHOULD WE USE HCF OR LCM IN THIS WORD PROBLEMS?

Answer:

We have to use HCF

I hope this helps

Step-by-step explanation:

Given,

Length = 8 m 25 cm = 8.25 m

Breadth = 6 m 75 cm = 6.75 m

Height = 4 m 50 cm = 4.5 m.

The longest rod that can measure all 3 dimensions of room exactly is their H.C.F.

      4.5 ) 6.75 ( 1

           

              4.50

       -----------------

             2.25 ) 4.5 ( 2

                        4.5

                  -------------

                         x

So, H.C.F of 4.5 m and 6.75 m is 2.25 m.

Now ,

       2.25 ) 8.25 ( 3

                 6.75

           --------------

                 1.5 ) 2.25 ( 1

             

                          1.5

                      ------------

                         0.75 ) 1.5 ( 2

                                   1.5

                               -------------

                                     x

So, the H.C.F of 8.25 m , 6.75 m and 4.5 m is 0.75 m.

Hence , answer is 0.75 m ( 75 cm ).

   I think my answer is capable to clear your problem.....✔️✔️✔️
