Question 44: Given the fraction \(\frac{{ – 80}}{{70}}\). Simplifying fractions to the simplest fractions, we get:

A. \(\frac{{ 8}}{7}\)

B.

\(\frac{{ – 11}}{7}\)

C. \(\frac{{ 11}}{7}\)

D. \(\frac{{ – 8}}{7}\)

\(\frac{{ – 80}}{{70}} = \frac{{\left( { – 80} \right):10}}{{70:10}} = \frac{{ – 8}} {7}\)

Question 39: Let \(\begin{array}{l} A = \left[ { – \sqrt {2,25} + 4\sqrt {{{\left( { – 2,15} \right)}^2}} – {{\left( {3\sqrt {\frac{7}{6}} } \right)}^2}} \right].\sqrt {1\frac{9}{{16}}} \\ B = 1.68 + \left[ {\frac{4}{5} – 1,2\left( {\frac{5}{2} – 1\frac{3}{4}} \right)} \right]:\left[ {{{\left( {\frac{2}{3}} \right)}^2} + \frac{1}{9}} \right] \end{array}\). Compare A and B. »
