kherson [118]

Answer:

3/4

Step-by-step explanation:

To answer this question we must first calculate the area of GHJK:

  • A= GH*HJ
  • A= (LM/2)* (MN/2)
  • A= LM*MN/4
  • LM/MN is the area of LMNO
  • So the area of LMNO is 4 times the area of GHJK
  • A is the area of LMNO and S the area of GHJK
  • S= A/4
  • A-S= A-A/4 = 3A/4
  • so the area that is not shaded is 3/4

If 23/8, 11/2, 9/6, and 15/7 are placed in order from least to greatest, which would be first?
yarga [219]

Answer:

\frac{9}{6}

Step-by-step explanation:

The given fractions are;

\frac{23}{8},\frac{11}{2},\frac{9}{6},\frac{15}{7}

The least common denominator is 168.


We express all the fractions in equivalent form with the LCD as the denominator.


\frac{23}{8}=\frac{21\times23}{21\times8}=\frac{483}{168}


\frac{11}{2}=\frac{84\times11}{84\times2}=\frac{924}{168}


\frac{9}{6}=\frac{28\times9}{28\times6}=\frac{252}{168}


\frac{15}{7}=\frac{24\times15}{24\times7}=\frac{360}{168}


We now compare the equivalent forms and arrange from the least to the greatest.

\frac{252}{168}\:

This implies that,

\frac{9}{6}\:

Therefore the first would be \frac{9}{6}.
