Question

Order these numbers from least to greatest.186-145, 12- 12.10'7'

Answer 1

`-(5)/(21)`

Step-by-step explanation:

Given the below;

`-(2)/(3)+(3)/(7)`

To add the above, the 1st step is to determine the LCM of 3 and 7.

Since 3 and 7 are prime numbers, therefore their LCM will be their product ( 3 x 7 = 21). So we'll have;

`-(2)/(3)+(3)/(7)=(-14+9)/(21)=-(5)/(21)`
