9/10 is given as the fraction of the crates filled with animals , 1/2 of this fraction holds dog , that is

1/2 of 9/10

= 1/2 x 9/10

= 9/20

Therefore the fraction of the total number of crates holding dog is 9/20

Give an example of fractions that you would compare by finding common denominators and an example of fractions you would compare

ziro4ka [17]

Answer:

Fractions can be compared both by finding the common numerators and denominators.

Step-by-step explanation:

The fractions can be compared by finding the common denominators, as an example consider the fractions

$\frac{2}{3}$ and $\frac{5}{6}$

To compare the two fractions we must find their common denominator, which is the least number divisible by both 3 and 6. The common denominator is 6.

Thus

$\frac{2}{3}=\frac{2*2}{3*2}=\boxed{\frac{4}{6}.}$

Now comparing this to $\frac{5}{6}$ we see that

$\frac{5}{6}>\frac{4}{6}$

Therefore

$\frac{5}{6}>\frac{2}{3}$

Thus fractions can be compared by finding the common denominators.

The fractions can be compared by finding the common numerators. As an example consider the fractions

$\frac{7}{2}$ and $\frac{7}{5}$

These fractions share the same numerators but different denominators. The denominator of 7/2 is less than that of 7/5, therefore we conclude that

$\frac{7}{2}>\frac{7}{5}$

This is how fractions are compared by finding the common denominators.
