Question

a)3/5 - 4/6=
b)1/2 + 1/3 + 1/4=
c)(-1/2)×(1/2)×(-1/2)=
d)10/3÷5/4
e)9-4/3
f)(-6)×(-2/5)

Answer 1

$a) \: \frac{3}{5} - \frac{4}{6} \\ \frac{3}{5} - \frac{2}{3} \\ \frac{9 - 10}{15} \\ \frac{ - 1}{15} \\ \\ b) \: \frac{1}{2} + \frac{1}{3} + \frac{1}{4} \\ \frac{6 + 4 + 3}{12} \\ \frac{13}{12} \\ \\ c) \: ( - \frac{1}{2} ) \times \frac{1}{2} \times ( - \frac{1}{2} ) \\ \frac{1}{8} \\ \\ d) \: \frac{10}{3} \div \frac{5}{4} \\ \frac{10}{3} \times \frac{4}{5} \\ \frac{2}{3} \times 4 \\ \frac{8}{3} \\ \\ e) \: 9 - \frac{4}{3} \\ \frac{27 - 4}{3} \\ \frac{23}{3} \\ \\ f) \: ( - 6) \times ( - \frac{2}{5} ) \\ \frac{12}{5}$
