What is the least common denominator of 6/30 and 8/40

The great thing about this problem is they give you everything you need to solve it easily. so the expression is: 12h+30w12h+30wand so everywhere you have an “h” you place 66. and everywhere you have a “w” you place 33. then the expression will look like this: 12(66)+30(33)12(66)+30(33)from here you multiply and then add. getting the following of: $785,862hope this

444(2)4-2(7)2+40=? 8(4)-14(2)+40=? 32-28+40=? 4+40=? 44
