Question

2целых 6/13(1/8-2целых9/16)=?

Answer 1

2целых 6/13(1/8-2целых9/16)=-6

1)1/8-2 9/16 =1/8-41/16=(2-41)/16=- 39/16=-2 7/16

2) 2 6/13 *(-2 7/16)=32/13* (-39/16)=-6

Answer 2

$2frac{6}{13}cdot(frac{1}{8}-2frac{9}{16})=-6$

 

1) $frac{1}{8}-2frac{9}{16}=frac{1}{8}-frac{41}{16}=frac{2-41}{16}=frac{-39}{16}=-2frac{7}{16}$

 

2) $2frac{6}{13}cdot(-2frac{7}{16})=frac{32}{13}cdot(-frac{39}{16})=-frac{32}{13}cdotfrac{39}{16}=-frac{2}{1}cdotfrac{3}{1}=-6$
