1.	Add the following:i. 3/15 + 4/15ii. 2/7 + 1/7 + 3/7iii. 2/10 + 4/10 + 3/10iv. 4/9 + 1/9
Answer» i. \(\frac{3}{15}+\frac{4}{15}=\frac{3+4}{15}=\frac{7}{15}\) ii. \(\frac{2}{7}+\frac{1}{7}+\frac{3}{7}=\frac{2+1+3}{7}=\frac{6}{7}\) iii. \(\frac{2}{10}+\frac{4}{10}+\frac{3}{10}=\frac{2+4+3}{10}=\frac{9}{10}\) iv. \(\frac{4}{9}+\frac{1}{9}=\frac{4+1}{9}=\frac{5}{9}\)

Add the following:i. 3/15 + 4/15ii. 2/7 + 1/7 + 3/7iii. 2/10 + 4/10 + 3/10iv. 4/9 + 1/9

Answer»

i. \(\frac{3}{15}+\frac{4}{15}=\frac{3+4}{15}=\frac{7}{15}\)

ii. \(\frac{2}{7}+\frac{1}{7}+\frac{3}{7}=\frac{2+1+3}{7}=\frac{6}{7}\)

iii. \(\frac{2}{10}+\frac{4}{10}+\frac{3}{10}=\frac{2+4+3}{10}=\frac{9}{10}\)

iv. \(\frac{4}{9}+\frac{1}{9}=\frac{4+1}{9}=\frac{5}{9}\)
