a. \(\dfrac{3}{5}\) : x = 3 => x = \(\dfrac{3}{5}\) : 3 = \(\dfrac{1}{5}\)
b. x - \(\dfrac{3}{4}\) = \(\dfrac{7}{10}\) => x = \(\dfrac{7}{10}+\dfrac{3}{4}=\dfrac{29}{20}\)
c. x : \(\dfrac{2}{3}=\dfrac{1}{2}+\dfrac{3}{4}=\dfrac{5}{4}\) =>x= \(\dfrac{5}{4}\)x\(\dfrac{2}{3}=\dfrac{5}{6}\)
a, 3/5:x=3 b,x-3/4 = 7/10 x :2/3 = 1/2+3/4
x= 3/5:3 x = 7/10 +3/4 x :2/3 = 5/4
x= 1/5 x = 29/20 x = 5/4 x 2/3
