Solve 10 3/4 - 6 4/5
MAXImum [283]
Alright, so the first thing I would do is find the LCM of the dividends, which is 20.  So we have 10 15/20 and 6 16/20.  You can either leave it there and just carry the one (20 in this case) for 3 19/20.
If you multiply 10 by 20 and add 15, or 6 by 20 and add 16 (which I think is easier) you get 215/20 - 136/20 = 79/20.  It can be simplified from here if you teacher wants it in the future.

Q: can you find the volume of the tank based on the opposite sides as the bases. 


This one was a tricky one lol. 

To find volume you need a formula: 

Formula for volume varies on the shape of the object.

<span><span>Cube = a 3<span>a is the side length

</span></span><span>Rectangular prism = a * b * c<span>a, b, c are the length, width, and height

</span></span><span>Cylinder = π * r 2 * h<span><span>r is the radius of the circular base</span><span>h is the height

for this one you would need the Rectangular prism formula. 

A: No you cannot find the volume because you need length, width, and height to figure out the volume of the rectangular prism. 

Hope this helped! :)

164 is 55% of what number?<br><br> Please somebody help me
monitta
This is how you solve it; but first of all convert the percent into a decimal;55%= 0.55

0.55x = 164 (divide by 0.55 on both sides)
x = 164/0.55 
x = 298.18 (rounded to the nearest hundredth)
so 164 is 55% of 298.18(rounded)
