Question

a,5+\(\dfrac{2}{3}\)

b,\(\dfrac{15}{5}\)x\(\dfrac{1}{4}\)

c.\(\dfrac{3}{8}\)\(-\)\(\dfrac{1}{3}\)

d,\(\dfrac{6}{15}\)\(-\)\(\dfrac{1}{3}\):\(\dfrac{5}{3}\)

Answer 1

a) 15/3 - 2/3 = 13/3

b) 15/20 = 3/4

c) 1/24

d) 2/5 - 1/5 = 1/5

Answer 2

a, = 17/3

b, = 3/4

c, = 1/24

d, = 6/15 - 1/5 = 1/5

Answer 3

a, \(\dfrac{5}{1}+\dfrac{2}{3}=\dfrac{15}{3}+\dfrac{2}{3}=\dfrac{17}{3}\)

b, \(3\times\dfrac{1}{4}=\dfrac{3}{1}\times\dfrac{1}{4}=\dfrac{3}{4}\)

c, \(\dfrac{3}{8}-\dfrac{1}{3}=\dfrac{9}{24}-\dfrac{8}{24}=\dfrac{1}{24}\)

d, \(\dfrac{6}{15}-\left(\dfrac{1}{3}:\dfrac{5}{3}\right)=\dfrac{6}{15}-\left(\dfrac{1}{3}\times\dfrac{3}{5}\right)=\dfrac{6}{15}-\dfrac{3}{15}=\dfrac{3}{15}=\dfrac{1}{5}\)

Answer 4

a.\(\dfrac{15}{3}-\dfrac{2}{3}=\dfrac{13}{3}\)                    b. \(\dfrac{15}{20}=\dfrac{3}{4}\)                c.\(\dfrac{1}{24}\)                  d.\(\dfrac{2}{5}-\dfrac{1}{5}=\dfrac{1}{5}\)
