250 years of one less than a number is less than 3/5 of one more than that number what number are And this solution set of this problem

y < 623.5

Step-by-step explanation:

Let the number be y

250yrs (1) - y < 3/5 (1) + y

250 - y < 3/5 + y

combine the like terms

250 - 3/5 < y + y

250 - 3/5 < 2y

make 250 and 3/5 a single fraction first by finding the LCM of 5 and 1 which is 5. Multiply by their LCM.

(250/1) 5 - (3/5) 5

1250 - 3 < 2y

1247 < 2y

divide both sides by 2

y < 1247/2

y < 623.5
