1.	of the three consecutive natural numbers, five times the smallest number is 9 more than four times the greatest number. find the numbers
Answer» Let the smallest of three be x. The second one is x+2 (why?) The third one is x+4; (why?) It is known that 5x=4(x+4); Five times the smallest equals four times the largest. From this, we obtain: 5x=4(x+4)=4x+16 x=16 x+2=18; x+4=20:

Answer»

Let the smallest of three be x.

The second one is x+2 (why?)

The third one is x+4; (why?)

It is known that 5*x=4*(x+4); Five times the smallest equals four times the largest.

From this, we obtain:

5x=4(x+4)=4x+16

x=16

x+2=18;

x+4=20:
