lcm(7, 20, 35) = 140 7 = 7 20 = 2^2 x 5 35 = 5 x 7 lcm = 2^2 x 5 x 7 = 140

7 x 420 = (7 x 400) + (7 x 20)

7 x 23 = (7 x 20) + (7 x 3)

x - 7 = 13 Therefore, x = 13 + 7 x = 20

Suppose the answer is x.Then x + 1/2 = 7/20 so that x = 7/20 - 1/2 = 7/20 - 10/20 = -3/20

-x + 7 = 27 Subtract 7 from both sides: -x = 20 or x = -20

lcm(7, 20, 35) = 140 7 = 7 20 = 2^2 x 5 35 = 5 x 7 lcm = 2^2 x 5 x 7 = 140

7 x 420 = 7(400 + 20) = 7 * 400 + 7 * 20.

7 x 420 = (7 x 400) + (7 x 20)

7 x 23 = (7 x 20) + (7 x 3)

x - 7 = 13 Therefore, x = 13 + 7 x = 20

1 x 20=20 7 x 1 = 7 20/7 make sure to convert into a mixed number like this: 2 6/7. <-answer

the answer is 140 .

The only common factor is: 1 20= 2 x 5 x 2 x 17 = 7 x 1The only common factor of 20 & 7 is 1

Suppose the answer is x.Then x + 1/2 = 7/20 so that x = 7/20 - 1/2 = 7/20 - 10/20 = -3/20

Factor them. 7 2 x 2 x 5 = 20 5 x 7 = 35 Combine the highest amount of each factor. 2 x 2 x 5 x 7 = 140, the LCM

7 x 420 = (7 x 400) + (7 x 20)
