The <u>percentage</u> of a given <em>number</em> in another implies the fraction of the given <em>numbe</em>r to that other number <em>with respect </em>to 100%. Thus the required <u>expression</u> is: x n
When a given number is written in<em> percentage</em>, it implies that the<em> fraction</em> of the number to the<u> total </u>number in relation to 100%. For example, to determine the <em>percentage</em> of a number r in s, -we have:
x 100%
Therefore in the given question, the required <em>expression</em> is;
m% =
So that;
m% of n can be <em>expressed</em> as;
x n

You could use a ratio form for the first question
4) 8.5 : 34
29.75 : x x is the unknown
To find x, you must divide 29.75 by the length 8.5 to find the amount needed to be multipled by 34 grams, to find the total grams needed for the length of 29.75
29.75 / 8.5= 3.5 34 x 3.5 = <u>119 grams</u> , which is the answer to 4)
5) Same for this question, use the ratio form
1 1/3 : 3/4 5 / 0.75 ( 3/4) = 6.7
x : 5 miles 6.7 x 1 1/3 = <u>8.91 Miles jack ran</u>
6) ?? (Question not shown)
7) n = 0.6
8) 1 patient : 25 mins
n patients : 7.5 hours
25 mins to hours = 0.4
1 : 0.4
n : 7.5 7.5 /0.4 = 18.75 ----> <u>19 patients</u>
The solutions of x are 1 and
Step-by-step explanation:
Given,quadratic equation is
[ here a =2, b= 3 and c= -5]
Either x =1 or,
Answer:L, Q & N, R
Step-by-step explanation:These both intersect eachother. hope this helps
