Answer:
Jacob is dividing 6 aquariums into 1/8 of an aquarium sections for his different animals. How many 1/8's are there in Jacobs aquariums?
To get the number of 1/8 in Jacobs aquariums,we simply divide 6 by 1/8
6 ÷ 1/8
But whenever you are dividing by a fraction, you can simply change the division to multiplication in order to make your work easier, all you need to do to change the division to multiplication is to simply turn the number over, that is; the denominator becomes the numerator and the numerator becomes the denominator,
In this case 8 becomes the numerator and 1 becomes the denominator
Hence;
6 × 8 /1 = 6 × 8 = 48
Therefore, the number of 1/8's in Jacobs aquariums are 48
Hope this helps, have a great day/night, and stay safe!
Lt1 = 45; Lt2 = 120; Lt3 = 75
:
Prime factor each:
45: 3,3,5,
120: 2,2,2,3,5
75: 3,5,5
:
Lcm of all three: 2,2,2,3,3,5,5 Multiply this: 1800 secs they will all Flash
:
1800/60 = 30 min: At 9:05Pm this should occur
