Question

Нйти значение выражение:

$8frac{3}{17}*5frac{1}{4}+3frac{14}{17}*5frac{1}{4}$

 

$3frac{4}{13}*15frac{3}{41}-3frac{4}{13}*2frac{3}{41}$

 

$(2frac{3}{4}+4frac{1}{8})*1frac{5}{11}$

Answer 1

1)5 1/4*(8 3/14+3 14/17)=5 1/4* 12=(21/4)*12=21*3=63

2)3 4/13*(15 3/41-2 3/41)=(3 4/13)*13=43

3)(22/8+33/8)*16/11=(55/8)*(16/11)=5*2=10

Answer 2

$1)5 frac{1}{4}*(8 frac{3}{14}+3 frac{14}{17})=5 frac{1}{4}* 12=frac{21}{4}*12=21*3=63 \  \2)3 frac{4}{13}*(15 frac{3}{41}-2 frac{3}{41})=(3 frac{4}{13})*13=43 \  \3)(frac{22}{8}+frac{33}{8})*frac{16}{11}=frac{55}{8}*frac{16}{11}=5*2=10$
