Tell whether the number is divisible by 2, 3, 4, 5, 6, 9 or 10.
1,125
![Page 7: CHAPTER 2 QUIZ REVIEW. 6 and 14 LCM = 42 6 = 2 x 3 14 = 2 x 7 LCM = 2 x 3 x 7.](https://reader035.fdocuments.in/reader035/viewer/2022062407/56649d755503460f94a55829/html5/thumbnails/7.jpg)
1, 125 is divisible by: 3, 5, and 9
1 + 1 + 2 + 5 = 9 and 9 is divisible by 3 and 9
1,125 has a 5 in ones place, so is divisible by 5

ANSWER:
1:00 PM 24 = 2 x 2 x 2 x 360 = 2 x 2 x 3 x 5
48 = 2 x 2 x 2 x 2 x 3 LCM = 24 x 3 x 5 = 240
240 ÷ 60 = 4 hours
9AM + 4 hours = 1 PM
