Question

(23*12/13)*13/24
27*3/16+27+13/16
32/35+7/15+38/35*7/15
​

Answer 1

$(23 \times \frac{12}{13}) \times \frac{13}{24} = 23 \times \frac{1}{2} = \frac{23}{2} = 11.5$

$27 \times \frac{3}{16} + 27 + \frac{13}{16} = \frac{27 \times 3}{16} + \frac{27 \times 16}{16} + \frac{13}{16} = \frac{27 \times 19 + 13}{16} = \frac{?}{16} = \frac{526}{16} = \frac{263}{8}$

$\frac{32}{35} + \frac{7}{15} + \frac{38}{35} \times \frac{7}{15} = \frac{5 \times 32 \times 3 + 49 \times 5 + 38 \times 7}{35 \times 15} = \frac{480 + 245 + 266}{3 \times 5 \times 5 \times 7} = \frac{991}{525}$
