3.12 (repeating) = 3 12/99 reduces to 3 4/33 or 103/33

if there is one number repeating, like 0.222...u put that one number over 9...making it 2/9.
if there is 2 numbers repeating, like 0.1313...u put the two repeating numbers over 99...making it 13/99
if there are 3 numbers repeating, like 0.123123...u put ur three repeating numbers over 999...making it 123/999

Determine the similarity ratio for each pair of similar solids.

Lostsunrise [7]

Answer:

a) $k = \frac{7}{4}$

b) ${k} = \frac{13}{9}$

Step-by-step explanation:

a) The similarity ratio is given by;

${k}^{2} = \frac{image \: size}{corresponding \: object \: size}$

This implies that:

${k}^{2} = \frac{78.4}{25.6}$

This simplifies to:

${k}^{2} = \frac{49}{16}$

Take positive square root:

${k} = \sqrt{ \frac{49}{16} }$

$k = \frac{7}{4}$

Therefore the similarity ratio is:

$k = \frac{7}{4}$

b) This time the size are in volumes: We still use the same approach. But this time:

${k}^{3} = \frac{175.76}{58.32}$

${k}^{3} = \frac{2197}{729}$

Take cube root:

${k} = \sqrt[3]{\frac{2197}{729} }$

${k} = \frac{13}{9}$

The similarity ratio is

${k} = \frac{13}{9}$
