Step-by-step explanation:
a. 25% of 84 = ?
To solve this problem;
[tex]\frac{25}{100}[/tex] x 84
25 goes in 100, 4 times
= [tex]\frac{1}{4}[/tex] x 84
= 21
b. [tex]\frac{24}{100}[/tex] x 200 = ?
100 goes in 200 , 2 times
24 x 2 = 48
c. [tex]\frac{10}{100}[/tex] of t = 5
[tex]\frac{10}{100}[/tex] x t = 5
[tex]\frac{t}{10}[/tex] = 5
t = 50
