Step-by-step explanation:

This question can be solved using a rule of three.

For each 5 non-fiction books, there are 9 fiction books. How many non-fiction books are there when there are 117 fiction books?

Find the hcf of 12,15 and 20​
yawa3891 [41]

HCF of 12 and 15 by Prime Factorization

1. As visible, 12 and 15 have only one common prime factor i.e. 3. Hence, the HCF of 12 and 15 is 3.

2. To find the HCF of 20 and 25, we will find the prime factorization of the given numbers, i.e. 20 = 2 × 2 × 5; 25 = 5 × 5. ⇒ Since 5 is the only common prime factor of 20 and 25. Hence, HCF (20, 25) = 5.

What is the solution to 3/2b + 5 < 17? Explain How.
jek_recluse [69]
<h3>3/2b + 5 < 17</h3>

<em>We subtract 5 from both sides of the inequality.</em>

<h3>3/2b + 5 - 5 < 17 - 5</h3><h3>3/2 b < 12</h3>

<em>Multiply both sides by 2/3.</em>

<h3>( 2/3) * (3/2b) < (2/3) * 12</h3><h3>b < 8</h3>

<em>Therefore, the </em><em>correct option</em><em> is </em><em>alternative "A".</em>

<em>We would think that it is </em><em>option B,</em><em> but the only difference is that it changes the</em><em> direction of the sign.</em>
