Step-by-step explanation:
Let the number to be found be x
<h2>a).</h2>
68 is what percent of 80 is written as
Multiply both sides by 100
We have
80x = 6800
Divide both sides by 80
we have the answer as
x = 85
<h3>Therefore the percentage is 85%</h3>
<h2>b).</h2>
Let the number be x
88.83 is 423% of what is written as
Multiply through by 100
We have
423x = 8883
Divide both sides by 423
We have the answer as
x = 21
<h3>The number is 21</h3>
<h2>c).</h2>
Let the number be x
36.8% of what number is 28.52 is written as
Multiply through 100
We have
36.8x = 2852
Divide both sides by 36.8
We have the answer as
x = 77.5
<h3>The number is 77.5</h3>
<h2>d).</h2>
What number is 95% of 40 is written as
We have the final answer as
<h2>38</h2>

Answer:
Step-by-step explanation:
The parallel lines divide each transversal proportionally.
x/30 = 15/26
x = 30(15/26) ≈ 17.3
__
y/16.5 = 26/15
y = 16.5(26/15) = 28.6
