luda_lava [24]

the next day 1/2 of 3/7 was eaten what remained is 3/7 divide by 1/2

ruslelena [56]
1. Decompose all numbers into prime factors
300 2 150 2 75 3 25 5 5 5 1 400 2 200 2 100 2 50 2 25 5 5 5 1 500 2 250 2 125 5 25 5 5 5 1
2. Write all numbers as the product of its prime factors
Prime factors of 300 = 22 . 3 . 52
Prime factors of 400 = 24 . 52
Prime factors of 500 = 22 . 53
3. Choose the common and uncommon prime factors with the greatest exponent
Common prime factors: 2 , 5
Common prime factors with the greatest exponent: 24, 53
Uncommon prime factors: 3
Uncommon prime factors with the greatest exponent: 31
4. Calculate the Least Common Multiple or LCM
Remember, to find the LCM of several numbers you must multiply the common and uncommon prime factors with the greatest exponent of those numbers.
LCM = 24. 53. 31 = 6000

#9 . . . #12, and #14:  Excellent.  All correct, and good estimates.

#13:  A very picky comment: 
Your math is correct, but the camera can't take 2/3 of an image. 
That's why the question asked "How many complete images ...".
After 66 images, there is still some time remaining, but not enough
for another image.  So it captures 66 complete images in 3 seconds.


If you are really in elementary school, then I think you're doing
the work of a prodigy.  Keep it up !  And best of luck to you.
