Answer:
$63
Step-by-step explanation:
<em>I believe you meant Richard worked for 7 </em><em>hours</em> and made $9 per hour.
In order to know how much Richard earned for 7 hours, you have to <u><em>multiply Richard's salary rate with his number of working hours.</em></u>
- 7 hours x 9 dollars/hour = $63
Therefore, Richard earned $63 for his 7-hour work.
<u>Additional Information</u>
Another example is: if Richard worked for 10 hours, you just have to multiply his salary rate again to his number of working hours.
- 10 hours x 9 dollars/hour = $90
Por lo tanto el número es p/q = 8/64.
<h3>¿Qué es una fracción?</h3>
Fracción es un número que se puede representar en forma de p/q, donde q no es igual a cero.
It is given that :
En su forma más simple, el número es 1/8
Sea el número p/q
p + q = 72 (dado)
p/q = 1/8
q = 8p
p+8p = 72
9p = 72
p = 8
q = 8p
q = 8 * 8 = 64
Por lo tanto el número es p/q = 8/64.
