e)3intregi1/4+2intregi1/6):5/6
f)(2intregi5/8-1intregi3/4)×13/7​

Answer 1

a)

$( \frac{11}{8} + \frac{1}{6}) \div \frac{37}{5}$

$\frac{37}{24} \frac{5}{37}$

$\frac{1}{24} \times 5$

$\frac{5}{24}$

b)

$( \frac{11}{8} - \frac{3}{4} ) \div \frac{1}{2}$

$\frac{5}{8} \times 2$

$\frac{5}{4}$

c)

$( \frac{11}{24} + \frac{11}{36}) \div \frac{11}{6}$

$\frac{11}{72} \times \frac{6}{11}$

$\frac{1}{12}$

d)

$( \frac{11}{6} - \frac{5}{9} ) \div \frac{23}{5}$

$\frac{23}{18} \times \frac{5}{23}$

$\frac{1}{18} \times 5$

$\frac{5}{18}$
