Question

сколько будет 7-1 4/5*(1 1/4+1/12):3

Answer 1

$7- 1frac{4}{5}*( 1frac{1}{4} +frac{1}{12}):3= 6,2$

$1) 1frac{1}{4} + frac{1}{12}= frac{5}{4}+ frac{1}{12}= frac{15+1}{12}= frac{16}{12}=1 frac{4}{12}=1 frac{1}{3}$

$2) 1frac{4}{5}*1 frac{1}{3}= frac{9*4}{5*3}= frac{12}{5}=2,4$

$3)2,4:3=0,8$

$4)7-0,8=6,2$
