It is 7 over 3, or 2 and 1 over 3.
2/7 - 4/7 = -2/7
The LCM is 210.
Oh, dude, let me break it down for you. So, if the greatest common factor (GCF) is 7 and the least common multiple (LCM) is 210, the number pairs would be multiples of 7 that multiply to 210. So, the number pairs would be 7 and 210. That's it. Easy peasy lemon squeezy.
The smallest number with 4 different prime factors can be found by multiplying the first four prime numbers together. These prime numbers are 2, 3, 5, and 7. Multiplying them together gives us 2 x 3 x 5 x 7 = 210. Therefore, 210 is the smallest number with 4 different prime factors.
4/7
4/7
4/7 + 18/21 = 210/147 or 10/7 or 13/7
210/7 = 210 ÷ 7 = 30
1/7 of 210 = 30 4/7 of 210 = 30 x 4 = 120
Divide 98 and 210 by their GCF, 14 210/98 = 15/7 or 2 and 1/7
180/210 = 6/7
210 / 240 = 7/8
180/210 = 18/21 = 6/7
168/210 = 4/5
It is 210 hope this is right
24 over 210 in its simplest form is 4 over 35.
