Question

Answer 1

a) \(\dfrac{5}{10}\) - \(\dfrac{2}{15}\)

= \(\dfrac{1}{2}\) - \(\dfrac{2}{15}\)

= \(\dfrac{11}{30}\)

b) \(\dfrac{5}{20}\) - \(\dfrac{1}{6}\)

= \(\dfrac{1}{4}\) - \(\dfrac{1}{6}\)

= \(\dfrac{1}{12}\)

c) \(\dfrac{6}{18}\) - \(\dfrac{6}{24}\)

= \(\dfrac{1}{3}\) - \(\dfrac{1}{4}\)= \(\dfrac{1}{12}\)d) \(\dfrac{5}{9}\) - \(\dfrac{3}{12}\)= \(\dfrac{5}{9}\) - \(\dfrac{1}{4}\)= \(\dfrac{11}{36}\)

a: =1/2-2/15=15/30-4/30=11/30

b: =1/4-1/6=1/12

c: =1/3-1/4=1/12

d: =5/9-1/4=20/36-9/36=11/36
