Question

Which is greater , the product of -7/6 and 2/9 or the product of 20/21 and 7/10, and by how much ?

Answer 1

Answer:

the product of 20/21 and 7/10 is greater than the product of -7/6 and 2/9 by 25/27

Step-by-step explanation:

$= > - \frac{7}{6} \times \frac{2}{9} = - \frac{7}{27} \\ \\ = > \frac{20}{ 21} \times \frac{7}{10} = \frac{2}{3} \\ \\ \\ = > \frac{2}{3} > ( - \frac{7}{27} ) \\ \\ \\ \\ = \frac{2}{3} - ( - \frac{7}{27} )\\ \\ = \frac{2}{3} + \frac{7}{27} \\ \\ = \frac{18 + 7}{27} \\ \\ = \frac{25}{27}$
