Hii! Could you help me? What are the ways or procedures to find LCM or LCD? Thanks in Advance! :))

Another method to find out the LCM of two or more than two numbers is here.. FIRST you have to find the largest number from all of the given numbers. SECONDLY check the coming multiples of that number which is divisible by all the given numbers. The multiple you get from this step is the LCM of the given numbers.

use an equation of ratios to determine the amount of gas needed to fill the tank.

    0.2             0.8

  =    

288.75             x

                                                              231 gal

so, 0.2x = (0.8)(288.75 gal), and x = = 1155 gal.

                                                                0.2

it would take 1155 gal. to fill the tank.

the cost would be

1155 gal         $3

* = $3465   (answer)

      1           1 gal

hope this you
