Find the counting number A, if GCF(A,6)=2 and LCM(A,6)=42

Mathematics
1 answer:
bonufazy [111]4 years ago
3 0

Answer:

The value of A is 14.

Step-by-step explanation:

We have LCM of (A,6) = 42

Assume A as 42/6 = 7

But we also have GCF (A,6) = 2

7 cannot be divided by 2 so, value of A is not 7.

Assuming next value,

             A = 42 x 2 / 6 = 14

We know that LCM of 14 and 6 is 42

GCF of 14 and 6 is 2.

The value of A is 14.

Divide a line of 1.8m into three parts in the ratio of 5:7:8​
kozerog [31]

Answer:

0.45 m, 0.63 m, 0.72 m

Step-by-step explanation:

Let the three parts of the line be 5x, 7x and 8x

Therefore,

5x + 7x + 8x = 1.8

20x = 1.8

x = 1.8/20

x = 0.09

5x = 5*0.09 = 0.45 m

7x = 7*0.09 = 0.63 m

8x = 8*0.09 = 0.72 m
