Answer:
Blue: 13/100 = 0.13 = 13%
Purple: 130/100=1.3=130%
Step-by-step explanation:
The picture shows 100 cubes in a grid that's 10 by 10. This means the shaded amount is a number out of 100. The first is 13 out of 100 which converts to 0.13 and 13%. The second has all the cubes shaded which means 100/100 which is 1 or 100% plus the last has 30 cubes out of 100 which converts to 0.30 or 30%. Together this makes 130/100 or 1.30 or 130%.
Answer:
Step-by-step explanation:
<u>1- digit numbers: </u>
- 1 to 9, number of digits = 9
<u>2- digit numbers:</u>
- 10 to 99, number of digits = 2(99 - 9) = 180
<u>3- digit numbers:</u>
- 100 to 999, number of digits = 3(999 - 99) = 2700
This is more than we have, but we know the number of pages is 3-digit.
<u>Let it be x, then we have:</u>
- 9 + 180 + 3(x - 99) = 1074
- 3(x - 99) = 1074 - 189
- 3(x - 99) = 885
- x - 99 = 885/3
- x - 99 = 295
- x = 295 + 99
- x = 394
