Ratio 5:2 as fraction should be 5/2
as you know 5/2 = 2.5
This is the biggest compared to 9/5, 8/5 and 2/7
9/5 < 2
8/5 <2
2/7 < 1
so 5/2 is greatest
<h2>
Forming Equations from Word Problems</h2>
To form equations from word problems, we can derive mathematical operations as well as variables from the given information.
In this case, each time Walker reads a certain number of pages, we subtract that from the total number of pages left to know how many pages is left to read.
<h2>Solving the Question</h2>
<em>Let r represent the pages left to read.</em>
<em />
792 pages in total
Walker reads 15 pages a day during the week and 25 pages a day during the weekend.
- There are 5 weekdays, and he reads 15 pages each of those days. ⇒ <em>r</em> = 792 - 5×15
- There are 2 weekend days, and he reads 25 pages each of those days.
⇒ <em>r</em> = 792 - (5×15 + 2×25)
5 weeks have passed
- Multiply the terms representing the number of pages he reads a week by 5, for 5 weeks.
⇒ <em>r</em> = 792 - (5×15 + 2×25)×5
<h2>Answer</h2>
<em>r</em> = 792 - (5×15 + 2×25)×5
Answer:
it's either A or B so try B
Step-by-step explanation:
Area: 153.9m
formula: 3.14(r^2)
7^2= 49
3.14•49=153.86
153.86 rounded is 153.9
