Step-by-step explanation:
We need to tell that which is greatest the sum of -7/10 and 3/7 or the sum of -1/8 and 15/25 and by how much.
Taking, [tex]\dfrac{-7}{10}+\dfrac{3}{7}=\dfrac{-19}{70}[/tex]
Taking, [tex]\dfrac{-1}{8}+\dfrac{15}{25}=\dfrac{19}{40}[/tex]
So, the sum of [tex]\dfrac{-1}{8}+\dfrac{15}{25}[/tex] is greater than the sum of [tex]\dfrac{-7}{10}+\dfrac{3}{7}[/tex].
To find how much :
Taking [tex]\dfrac{19}{40}-\left(-\dfrac{19}{70}\right) = \dfrac{209}{280}[/tex]
Hence, this is the required solution.
