8(-3/2x+6)=-9(4/3x-8)

I’m still confused on how to work the percentages

Maria found the least common multiple of 6 and 15. her work is shown below. multiples of 6: 6, 12, 18, 24, 30, 36, 42, 48, 54, 60, . . multiples of 15: 15, 30, 45, 60, . . the least common multiple is 60. what is maria's error?

The diagram shows a cuboid abcdefgh abcd is a square with area 25cm². find the volume of the cuboid.
