6) 3/5 – 2/6=…

Pertanyaan :

6 ) 3/5 – 2/6=

7 ) 3 – 1 4/6 =

8 ) 6 1/2 – 3 3/5 =

9 ) 0,5 + 2 1/4 =

10 ) 159,6 + 23, 46 =

Jawaban dan Penjelasan :

6 )

$frac { 3 } { 5 } - frac { 2 } { 6 } =frac{3}{5}-frac{1}{3} frac{9}{15}-frac{5}{15} = frac{9-5}{15} = frac{4}{15}$

7 )

$3 - 1 frac { 4 } { 6 } = 3-frac{6+4}{6} = 3-frac{10}{6} = 3-frac{5}{3} \ \ = frac{9}{3}-frac{5}{3} = frac{9-5}{3} = frac{4}{3} = 1 frac{1}{3}$

8 )

$6 frac { 1 } { 2 } - 3 frac { 3 } { 5 } = frac{12+1}{2}-frac{3times 5+3}{5} \ \ = frac{13}{2}-frac{3times 5+3}{5} = frac{13}{2}-frac{15+3}{5} \ \ = frac{13}{2}-frac{18}{5} = frac{65}{10}-frac{36}{10} = frac{65-36}{10} \ \ = frac{29}{10} = 2 frac{9}{10}$

9 )

$0 , 5 + 2 frac { 1 } { 4 } = sort(0,5+frac{8+1}{4}) \ \ = sort(0,5+frac{9}{4}) = sort(0,frac{20}{4}+frac{9}{4}) \ \ = sort(0,frac{20+9}{4}) = sort(0,frac{29}{4}) \ \ = 0,frac{29}{4}$

10 )

$159.6 + 23.46 = 183.06$
