Question

3 7/10 + 6 3/10 - 5 5/10
1 - 3/14
5 3/8 - 2 5/8

Answer 1

$3 \frac{7}{10} +6\frac{3}{10} -5\frac{5}{10} =\frac{37}{10} +\frac{63}{10} -\frac{55}{10} =\frac{45}{10} =4.5\\\\1-\frac{3}{14} = \frac{14}{14} -\frac{3}{14} =\frac{11}{14} \\\\5\frac{3}{8} -2\frac{5}{8} =\frac{43}{8} -\frac{21}{8} =\frac{22}{8} =\frac{11}{4} =2\frac{3}{4}$
