Question

a) 2/3 + 1/5 - 3/4 =
b) 3/4 . 2/3
c) 5/6 : 1/2 =
d) 3/7 + 2/5 - 1/3

Answer 1

a) $\frac{2}{3} + \frac{1}{5} - \frac{3}{4} = \frac{40+12-45}{60} = \frac{12-5}{60} = \frac{7}{60}$

b) $\frac{3}{4}*\frac{2}{3} = \frac{6}{12} = \frac{1}{2}$

c) $\frac{\frac{5}{6} }{\frac{1}{2} } = \frac{5}{6} * 2 = \frac{10}{6} = \frac{5}{3}$

d) $\frac{3}{7}+\frac{2}{5} -\frac{1}{3}=\frac{45+42-35}{105} = \frac{52}{105}$
