The HCF of the numbers 18 and 40 is 2.

The common factors of 18 and 40 are: 1, 2.

The greatest common factor is the highest number that divides exactly into two or more numbers. 18: 1, 2, 3, 6, 9, 18 40: 1, 2, 4, 5, 8, 10, 20, 40 The GCF for 18 and 40 is 2.

LCD(5, 8) = 40.So 3/5 = 24/40 and 5/8 = 25/40. The second fraction, that is 5/8, is greater.

3 over 40 can not be simplified further.

LCD(5, 18) = 90

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

LCD(32, 40) = 160

LCD(33, 40) = 1320LCD(33, 40) = 1320LCD(33, 40) = 1320LCD(33, 40) = 1320

18/40 = 0.45

1 = 1/1, 40 = 40/1 so LCD(1, 40) = 1.

18 = 9 40 20

NO. 18/20 is not proportional to 34/40. 18/20 : 34/40 by cross multiplication 18 * 40 = 20 * 34 720 ≠ 680 thus 18/20 is not proportional to 34/40

18/40 = 9/20 = .45

LCD(40, 50) = 200
