1. What is the average of the smallest and the greatest three-digit numbers that aredivisible by 18?(1) 545 (2) 645 (3) 549 (4) 64912 |

Answer» The smallest three digit no is 100. The largest three digit no is 999 If you divide the above two figures seperately by 18 you will get a quotient and a reminder. If the reminder is not zero you multiply the quotient incresed to the nearest whole number by 18 to get the smallest and largest three digit number divisible by 18. Add the two and divide the sum by 2 to get the average. 100÷18=5.5. 18*6=108 999÷18=55.55. 18*55=990 (108+990)=1098/2=549 hit like if you find it useful thank you |
