Use prime factorization to reduce each fraction 1. 22/165 2. 35/210

yKpoI14uk [10]

Lets find the prime factorization of 22, 165, 35 and 210. Prime factorization of a number is breaking a number down into the set of prime numbers which multiply together to result in the original number.

The prime factorization of the number 22 is:

$22=2\times11$

Similarly, for 165, 35 and 210 we have

$\begin{gathered} 165=3\times5\times11 \\ 35=5\times7 \\ 210=2\times3\times5\times7 \end{gathered}$

Then, we can solve the given questions.

Question 1.

$\frac{22}{165}=\frac{2\times11}{3\times5\times11}$

so we can cancel out the number 11 and get

$\frac{22}{165}=\frac{2}{3\times5}=\frac{2}{15}$

Then, the answer is

$\frac{2}{15}$

Question 2.

$\frac{35}{210}=\frac{5\times7}{2\times3\times5\times7}$

and we can cancel out the number 5 and 7, then we obtain

$\frac{35}{210}=\frac{1}{2\times3}$

then, the answer is

$\frac{1}{6}$

How many flowers, spaced every 4 in., are needed to surround a circular garden with a 100-ft radius? use 3.14

IRINA_888 [86]

Answer:

<h2> 157</h2>

Step-by-step explanation:

Let us first calculate the circumference of the circular of the circular garden

$C= 2\pi r$

Given

r= 100

$C= 2*3.142*100\\C= 628.4 ft$

Since the desired space between flowers is 4ft

Then the flowers needed for the garden is $\frac{628.4}{4} = 157.1$

Approximately the number of flowers is 157
