Question

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

Answer 1

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

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

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