\(\frac{3}{4}\) எடை கொண்ட செங்கலின் எடை \(\frac{7}{8}\) கிகி

கணக்கீடு:

செங்கலின் டை x கிகி ஆக இருக்கட்டும்.

கேள்வியின் படி,

\(\frac{3}{4}\) × x = \(\frac{7}{8}\)

⇒ x = \(\frac{7}{6}\)

\(\frac{5}{7}\) எடை கொண்ட செங்கலின் எடை = \(\frac{7}{6}\) × \(\frac{5}{7}\) = \(​\frac{5}{6}\) கிகி

\(\frac{5}{7}\) எடை கொண்ட செங்கலின் எடை \(​\frac{5}{6}\) கிகி ஆகும்.
