Q. Sheila's skates weigh 4 lbs. 3 oz., Heidi's skates weigh 3 lbs. 7 oz., and Javier's skates weigh 3 lbs. 13 oz. what is the average weight of the four skate pairs of skates?
-
A. Do I just add them all??
Kk so 15 lbs. 24 Oz divided by 4 equals??
You have to add all together, then take that sum and divide it by how many numbers there are. For instance you have 3 numbers . So you would do 4.3 + 3.7 + 3.13 which equals 11.13. Then you take that number and divide it by 3 which is equal to 3.71 or just 3.7 depending on if you teacher makes your round or not.
Hope this helped.. Ask anymore question Ill try my best to answer them while Im online (:
so the answers is 3.71 ? Andthanks
don't you have 2 like um... divide 15.24 by 4 and get a quotient like 3.81... ps I'm in 5th grade but trust me and my teachers I'm... SMART
To find the average weight of the four skate pairs, you need to add up the weights of all the skate pairs and then divide the sum by 4. Here's the step-by-step process:
1. Convert the weights to a consistent unit. In this case, let's convert all the weights to ounces, as it is a smaller unit than pounds and will allow for more precise calculations.
- Sheila's skates weigh 4 lbs. 3 oz., which is equivalent to (4 * 16) + 3 = 67 oz.
- Heidi's skates weigh 3 lbs. 7 oz., which is equivalent to (3 * 16) + 7 = 55 oz.
- Javier's skates weigh 3 lbs. 13 oz., which is equivalent to (3 * 16) + 13 = 61 oz.
2. Add up the weights of all four pairs of skates:
67 oz + 55 oz + 61 oz = 183 oz
3. Finally, divide the sum by 4 to find the average weight:
183 oz / 4 = 45.75 oz.
Therefore, the average weight of the four pairs of skates is approximately 45.75 ounces.
Yeah it is and no problem.. But like i said don't forget to put it as 3.7 (only if your teacher is picky about rounding)
15.24 divided by 24 equals 0.64..
BUTTT..
Make sure you know the order of the problem because by simply switching 15.24 and 24 make a difference sooo..
24 divided by 15.24 equals 1.57 (1.6)
See the difference? so make sure you know the order and it will one of those two answers I provided for you.
