Question

вычислите 2,5-0,4*3 1/3

Answer 1

2,5-0,4*3 1/3= 2.5-1 1/3 = 1 1/6

Answer 2

$2,5-0,4cdot3frac{1}{3}=1frac{1}{6}$

 

1) $0,4cdot3frac{1}{3}=frac{4}{10}cdotfrac{10}{3}=frac{4}{3}=1frac{1}{3}$

 

2) $2,5-1frac{1}{3}=2frac{5}{10}-1frac{1}{3}=2frac{1}{2}-1frac{1}{3}=frac{5}{2}-frac{4}{3}=frac{15-8}{6}=frac{7}{6}=1frac{1}{6}$
