Same as finding the LCM of 6, 5, 7: 2*3*5*7 = 210
23/35
sixteen fifths 16/5 = 3 1/5
4/5+2/7=38/35 which is equal to 1 and 3/35
1/2 x 3/7 = 3/14
3/5 + 7/8 + 6/7 = 2 93/280
30/140 = 3/14
We convert it into thirty-fifths. That gives 15 thirty-fifths minus 14 thirty-fifths which is one thirty fifth.
3/7 x 4/5 = 12/35
1
3 sevenths
(3/5) * (4/7) = (3*4)/(5*7) = 12/35.
two and 3 fifths
7/10 divided by 2/5 is 1.75 or 1 3/4
Nine and three sevenths can be converted into 66 sevenths. Three and four fifths can be converted into 19 fifths. Then I'll convert both fractions into 35ths, so we have 330 35ths minus 133 35ths, so, we get 197 35ths, which simplified to five and 22 35ths.
Expressed as a decimal, 5 4/5 + (-3 2/7) = 2.5142857 recurring (that is, 2.5142857142857...)
5/7, 1/2, 3/5 LCM is 70
