Question

Compare -3.5 and -10/3 using symbols <, >, or =.

Answer 1

Answer:

$\sf A. \quad -3.5 < -\dfrac{10}{3}$

Step-by-step explanation:

Convert -3.5 into a fraction:

$\implies \sf -3.5=-\dfrac{35}{10}=-\dfrac{\diagup\!\!\!\!5 \times 7}{\diagup\!\!\!\!5 \times 2}=-\dfrac{7}{2}$

Rewrite both fractions so that they have the same denominator:

$\implies \sf -\dfrac{7}{2}=-\dfrac{7 \times 3}{2 \times 3}=-\dfrac{21}{6}$

$\implies \sf -\dfrac{10}{3}=-\dfrac{10 \times 2}{3 \times 2}=-\dfrac{20}{6}$

$\textsf{As }\: -\dfrac{21}{6} < -\dfrac{20}{6} \textsf{ then}:$

$\sf \implies -3.5 < -\dfrac{10}{3}$
