Question

(25,05-1)/(1/3-1/7)=

Answer 1

1)25,05-1=24,05
2)1/3-1/7=7/21-3/21=4/21
3)24,05:4/21=24 5/100:4/21=24 1/20:4/21=481/20*21/4=10101/80=126 21/80

Answer 2

$(25.05-1)/( frac{1}{3} - frac{1}{7} )=126 frac{21}{80} \ 1)25.05-1=24.05 \ 2) frac{1}{3} - frac{1}{7} = frac{7}{21} - frac{3}{21} = frac{4}{21} \ 3)24 frac{1}{20} : frac{4}{21} = frac{481}{20} * frac{21}{4} = frac{10101}{80} =126 frac{21}{80}$
