Well I am assuming you want to compare them or something so yeah:
You have to find a common denominator of 4 & 6, so you could multiply them together, this makes 24. Because you have to do the same thing to the top and the bottom, you have to multiply 2/4 (which is now 2/24) by 6, and the 2/6 (which again is 2/24) by 4 which leaves you with 12/24 (2/4) and 8/24 (2/6).
We can simplify these fractions by dividing them, but as you may know 12 is half of 24 so 12/24 would also be 1/2.
If you keep dividing by 2 you will find that 8/24 is also equal to 1/3. This is easier to find out by the beginning number but I mentioned it anyway because I didn't understand what you were asking.
Overall if you noticed when comparing 2/4 and 2/6 we found that Mei Lyn painted more wall than Mario.
V=2πrh
28.27=(2)(3.14)(1.5)h
h=28.27/(2)(3.14)(1.5)
h≈3
answer c. 3.0
0.72 repeating is the sum of a geometric series with first term 0.72 and common factor 1/100. The sum is given by:
(first term) 0.72 0.72 72
--------------------------- = --------------- = ------------ = ------------
1 - common factor 1 - 1/100 99/100 99
This 72/99 can be reduced to 8/11.
0.72 repeating can be rewritten as the fraction 8/11.
Answer:
D
Step-by-step explanation:
for 20 pounds of grass seed, we need 356 pounds of fertilizer
20 pounds of grass seed : 356 pounds of fertilizer
divide both sides by 20 to get 1 pound of grass seed on one side, as we want to figure out the corresponding amount of fertilizer for 1 pound of grass seed
20 pounds of grass seed/20 : 356 pounds of fertilizer/20
1 pound of grass seed: 17.8 pounds of fertilizer
Well, estimate means to get like a general idea, or "in the ball park".
The factors include; the trip which is $26, and the ammount of students in the class, which is 22.
In order to estimate, you need to round.
$26 rounded becomes $30.
22 rounded becomes 20.
So now that we have the rounded numbers, we solve the problem. In order to find the total cost for all the students, we multiply the amount of students, by the ammount of money it costs per student.
The estimated version of this is: 20x30=600
This means that the estimated answer is $600 total.
Now do the same thing with the actual numbers.
22x26=572.
This means that the actual answer is $572.
The roumded total
Answer is $600.
You can say it is better use the actual numbers, and not estimate, because it is the actual answer.
I hope this helps you, im sorry for the long answer :)
