Good Morning Mrs Avdi and Ms Robertson,
This Morning I answered the daily Maths Challenge and this is my answer below:
The book has 221 pages.
42 of the digits are a 5.
???
Page 1 to page 9 = 9 digits.
Page 10 to page 99=198 digits.
198 digits + 9 digits = 207 digits.
Page 100 to page 199 = 300 digits.
300 digits + 207 digits = 507 digits.
Page 200 to page 215 = 48 digits.
507 digits + 48 digits = 555 digits.
There are 215 pages.
43 of them are fives.
221 pages in the book.
42 numbers 5’s in the book.
221
24 or 44(50,51,52,53,54,55,56,57,58,59,150,151,152,153,154,155,156,157,158,159)
Hi guys! I hope you are all well.
Total number of pages in the book: 311
Total number of 5: 34
Hello everyone! I hope your day has been good so far. For today’s task I got these results.
1) The book has 221 pages.
Explanation:
1 – 99 = 99 digits
100 – 555 = 368 digits ÷ 3 = 122.6
122.6 + 99 = 221.6
2) There are 42 ‘5’ in 221 pages
Explanation:
There are 20 ‘5’ in every hundred: 5, 15, 25, 35, 45, 50, 51, 52, 53, 54 …
In the numbers 55 and 155 there are two ‘5’ and you count both.
I found this challenge extremely hard. This is how it felt ??????????????????????????????
Hello Mrs Avdiu and Ms Robertson, I hope your having a good Friday ?
For today’s maths challenge, I came up with these answers:
1. Jack’s book has a total of 278 pages. I divided 555 by 2 ( as there are 2 sides on each page) and got 277 remainder 1, which means 278 pages ( one side is blank).
2. There are 151 pages with the digit 5 . I found this out by counting pages with the digit 5 in every hundred pages. This came up to 19 pages which I multiplied by 5 (up to page 499). 19 x 5 =95. I then added 56 (pages from 500 to 555) and the total of this was 151.
I hope you all have a nice weekend?
Maia?
