Answer: Juan
Explanation:
Step 1: Find how many pages each person read.
ANA
15% of her 46 page book
Whenever you have something% OF something, you just turn the 'of' into a multiplication sign.
15% x 46
Next, turn 15% into a decimal. There are 3 ways to do this. (1. put a decimal point right before the number (2. move it 2 places to the right, (3. just divide by 100. Either way, 15% becomes 0.15
0.15x46= 6.9
Ana can read 6.9 pages in a day.
HILARY
11% of a 72 page book
Same method I used for Ana. turn "of" into multiplication, convert the percentage to a fraction by moving the point 2 places left, and multiply.
**11 is the same as 11.0, which becomes 0.11.**
11% x 72
0.11x72= 7.92
Hilary can read 7.92 pages in a day.
ROGER
12% of 68 pages
of becomes multiply
12% becomes 0.12 because 12 is the same as 12.0, and you move 12 2 places to the left.
now we have 0.12x68= 8.16
JUAN
14% of 69 pages
of becomes multiply, 14 is the same as 14.0, move it 2 places to the left and it becomes 0.14. boom.
0.14x69= 9.66
Juan can read 9.66 pages in a day.
Step 2: Line up all of the numbers and find the biggest one.
Ana: 6.9 pages per day
Hilary: 7.92 pages per day
Roger: 8.16 pages per day
Juan: 9.66 pages per day
9.66 is the greatest number.
Juan can read the most pages per day
Hope this helps :)
