Question

Answer 1

a: =33/15-20/15=13/15

b: =31/36-30/36=1/36

c: =10/3-9/3=1/3

d: =1-2/5-1/3=15/15-6/15-5/15=4/15

Answer 2

a : = \(\dfrac{33}{15}\) - \(\dfrac{20}{15}\) = \(\dfrac{13}{15}\)                                                                                                                                                                               b : = \(\dfrac{31}{36}\) - \(\dfrac{30}{36}\) = \(\dfrac{1}{36}\)    c : = \(\dfrac{10}{3}\) - \(\dfrac{9}{3}\) = \(\dfrac{1}{3}\)                               d : = 1 - \(\dfrac{2}{5}\) - \(\dfrac{1}{3}\)  = \(\dfrac{15}{15}\)   -  \(\dfrac{6}{15}\) - \(\dfrac{5}{15}\) =\(\dfrac{4}{15}\)
