Yes you need to! And you need to be careful not to forgot that when doing your calculations!!
Answer:
-0.333, -1/7, 1/8
Step-by-step explanation:
1/8 is the greatest because it is a positive number while the other two numbers are negative.
-0.333 or -1/3 is smaller than -1/7.
If you want to easily find the solution you can use your calculator.
Just divide 77 by 110 and see the result.
77/110 = 0.7 = 7/10 = 70/100 = 70%
100% - 70% = 30%
Explanation
110*x=77
x=77/110, but the answer is not a percent
So 77/110 = ?/100 => ?=77*100/110=70 => 70%
But since 70% does not represent a percentage decreasement, we need to subtract it from the 100%
100% - 70% = 30%
Lateral is 13.8cm
Total surface area is 32cm
You add 7+5 together to get 12, then you multiply 12 by 6 and get 72, then you add the 3 to 72 and get 75. 6(7+5)+3. Hope this helps with the problem!!
