Question

a)  3/5 + 1/2 = 

b)   3/2 + 5/4 + 5/8 = 

c) 1/6 + 4/5 + 5/2 = 

giải chi tiết thì sẽ có quà nha

Answer 1

a: 3/5+1/2=6/10+5/10=11/10

b: 3/2+5/4+5/8=12/8+10/8+5/8=27/8

c: 1/6+4/5+5/2=5/30+24/30+75/30=104/30=52/15

Answer 2

a \(\dfrac{11}{10}\)

b \(\dfrac{27}{8}\)

c \(\dfrac{52}{15}\)

Answer 3

a)\(\dfrac{3}{5}\)+\(\dfrac{1}{2}\)=\(\dfrac{6}{10}\)+\(\dfrac{5}{10}\)

            =\(\dfrac{6+5}{10}\)

            =  \(\dfrac{11}{10}\)

b)\(\dfrac{3}{2}\)+\(\dfrac{5}{4}\)+\(\dfrac{5}{8}\)=\(\dfrac{12}{8}\)+\(\dfrac{10}{8}\)+\(\dfrac{5}{8}\)

                 =\(\dfrac{12+10+5}{8}\)

                 =       \(\dfrac{27}{8}\)

c)\(\dfrac{1}{6}\)+\(\dfrac{4}{5}\)+\(\dfrac{5}{2}\)=\(\dfrac{5}{30}\)+\(\dfrac{24}{30}\)+\(\dfrac{75}{30}\)

                 =\(\dfrac{5+24+75}{30}\)

                 =      \(\dfrac{104}{30}\)

                 =       \(\dfrac{52}{15}\)
