Answer:

Step-by-step explanation:

To solve, I converted the fraction to decimals

1.5/(2.25-0.75) X 1.8 = 1.5/1.5 X 1.8 = 1.8

3.2 - 1.20 = 2

3(2/30 - 1/30) = 3(1/30) = 3/30 = 1/10 = 0.1

2(2/64 / 1/16) = 2(32/64) = 2 (1/2) = 1

1.8/0.1 + 2/1 = 18 + 2 = 20

$\dfrac{\displaystyle\binom{8}{2}}{\displaystyle\binom{12}{2}}=\\\\
\dfrac{\dfrac{8!}{2!6!}}{\dfrac{12!}{2!10!}}=\\\\\
\dfrac{8!}{2!6!}\cdot\dfrac{2!10!}{12!}=\\\\
\dfrac{7\cdot8}{2}\cdot\dfrac{2}{11\cdot12}=\\\\
\dfrac{7\cdot4}{11\cdot3}=\\\\
