Question

а) 48 : 12/13
б) 15/16 : 5
в) 4 3/4 : 1/4 - 2 3/14 • 7

Answer 1

48:$frac{12}{13}$=48*$frac{13}{12}$=52
$frac{15}{16}$:5=$frac{15}{16}* frac{1}{5}$=$frac{3}{16}$
$4 frac{3}{4}: frac{1}{4}-2 frac{3}{14}*7= frac{19}{4}*4- frac{31}{14}*7=19- frac{31}{2}= frac{38-31}{2}= frac{7}{2}= 3frac{1}{2}$
