Question

5-6/5+3/8 1/2+1/2:1/3 5/6-1/6×1/8

Answer 1

\(a,5-\dfrac{6}{5}+\dfrac{3}{8}=\dfrac{5.40-6.8+3.5}{40}=\dfrac{200-48+15}{40}=\dfrac{167}{40}\\ ----------\\ b,\dfrac{1}{2}+\dfrac{1}{2}:\dfrac{1}{3}=\dfrac{1}{2}+\dfrac{1}{2}.\dfrac{3}{1}=\dfrac{1}{2}+\dfrac{3}{2}=\dfrac{4}{2}=2\\ ----------\\ c,\dfrac{5}{6}-\dfrac{1}{6}.\dfrac{1}{8}=\dfrac{5}{6}-\dfrac{1}{6.8}=\dfrac{5}{6}-\dfrac{1}{48}=\dfrac{5.8-1}{48}=\dfrac{40-1}{48}=\dfrac{39}{48}=\dfrac{13}{16}\)

Answer 2

`5-6/5+3/8 = 25/5 - 6/5 + 3/8= 19/5 + 3/8=167/40`

`1/2+1/2:1/3= 1/2+ 1/2 xx 3= 1/2 + 3/2= 4/2= 2`

`5/6-1/6×1/8= 5/6-1/48= 40/48 - 1/48= 39/48=13/16`
