Answer:
Here, a watermelon is divided into 16 parts. \[\therefore \] each part \[=\frac{1}{16}\] I ate 7 parts out of 16 parts i.e. \[\frac{7}{16}\] part. My friend ate 4 parts out of 16 parts i.e., \[\frac{4}{16}\] part. Now, the part which we eat together \[=\frac{7}{16}+\frac{4}{16}=\frac{7+4}{16}\] \[=\frac{11}{16}\] part Now, difference between our parts \[=\frac{7}{16}-\frac{4}{16}=\frac{7-4}{16}=\frac{3}{16}\] So, I ate \[\frac{3}{16}\] part of watermelon more than my friend. Now, remaining part of the watermelon \[=1-\frac{11}{16}\] \[=\frac{16}{16}-\frac{11}{16}\] [ \[\because \] \[\frac{16}{16}\] and 1 are equivalent fractions] \[=\frac{16-11}{16}=\frac{5}{16}\]
