Answer:
3 ÷ 0.25
Step-by-step explanation:
There are three squares, so 3.
Each square is divided into four squares,
One square out of four squares is,
1 / 4 = 0.25
Therefore,
3 ÷ 0.25
Let the required no. be x then according to question
(84/100)*x = 21
x = 21*(100/84)
x = 2100/84
x = 25
hence the required no. is 25
