Question

Зделайте 2 номера пж которые отмечены красным светом 10 номер и 11 пж

Answer 1

$10.\a);frac45+frac7{10}=frac8{10}+frac7{10}=frac{15}{10}=1frac5{10}=1frac12\\b);frac56+frac23=frac56+frac46=frac96=1frac36=1frac12\\c);frac8{15}+frac45=frac8{15}+frac{12}{15}=frac{20}{15}=1frac5{15}=1frac13\\d);frac7{12}+frac23=frac7{12}+frac8{12}=frac{15}{12}=1frac3{12}=1frac14$

$11.\a);frac12+frac23+frac56=frac36+frac46+frac56=frac{12}6=2\\b);frac25+frac3{10}+frac7{20}=frac8{20}+frac6{20}+frac7{20}=frac{21}{20}=1frac1{20}\\c);frac13+frac1{12}+frac1{24}=frac8{24}+frac2{24}+frac1{24}=frac{11}{24}$

Answer 3

№10

а)4/5+7/10=8/10+7/10=15/10=1.5/10=1.1/2

б)5/6+2/3=5/6+4/6=9/6=1.3/6=1.1/2

в)8/15+4/5=8/15+12/15=20/15=1.5/15=1.1/3

г)7/12+2/3=7/12+8/12=15/12=1.3/12=1.1/4

№11

а)1/2+2/3+5/6=3/6+4/6+5/6=7/6+5/6=12/6=2

б)2/5+3/10+7/20=8/20+6/20+7/20=14/20+7/20=21/20=1.1/20

в)1/3+1/12+1/24=8/24+2/24+1/24=10/24+1/24=11/24
