I would first convert to fractions then do the subtraction ( it will be a negative answer)
x = .02020202.....
100x = 2.02020202
99x = 2
x = 2/99
y = .002002002....
1000y = 2.002002...
999y = 2
y = 2/999
2/999 - 2/99 = (22- 222) / 10989 = -200 / 10989
If they work together, they will have an hour-long lunch instead. ???? Is this part correct?
Same thing.......find a common denominator of all THREE of the fractions and convert them.....
example 1/3 2/5 9/12
= 20/60 24/60 45/60
Here is one way to solve this
find the sum of the numerator n/2 (a1 + an) = 17/2(36) = 306
then the sum of the denominator = 17/2 (54) = 459
306/459 = 2/3
After working with fractions for a while, you may be able to 'feel' which is larger, but to be SURE, convert each to a fraction with a common denominator
4/5 = 8 /10
3/2 = 15 /10 Now you can easily see which is larger.......
Find the AREA of the triangular face 1/2 (base)(height)
then multiply the area by the LENGTH of the prism to find the volume in ft3
Not sure
To help 'cement' in the concepts you heard/learned in class. To commit these concepts/ideas to memory.....
.... and it keeps you out of trouble ! LOL
