20 30 40 56
LCD(40, 50) = 200
120
3k/40 +k/18 factoring 40=2*2*2*5 18=2*3*3 LCD=2*2*2*5*3*3 LCD=360
LCD(3, 40) = 120
It is: 40
If that's 3/8 and 7/10, the LCD is 40.If not, it's 13490
40. All three numbers will equal each other when they multiply to 40.
LCD(32, 40) = 160
LCD(33, 40) = 1320LCD(33, 40) = 1320LCD(33, 40) = 1320LCD(33, 40) = 1320
First you have to find the LCD. LCD=40 Then you multiply each fraction top and bottom to get 40 as the LCD. 35/40+32/40+18/40 Then you need to add. 85/40 Lastly you simplify. So the answer is 19/8(19 over 8)
40
