Answer 1

a. \(\frac{22}{55}\)+ \(\frac{25}{125}\)+ \(\frac{1020}{5100}\)

= \(\frac{2}{5}\)+ \(\frac{1}{5}\)+ \(\frac{1}{5}\)

= \(\frac{4}{5}\)

B. \(\frac{22}{77}\)+ \(\frac{56}{98}\)+ \(\frac{25}{105}\)

= \(\frac{2}{7}\)+ \(\frac{4}{7}\)+ \(\frac{5}{21}\)

= \(\frac{6}{7}\)+ \(\frac{5}{21}\)

= \(\frac{23}{21}\)
