• $\frac{1}{4} th$ are black beads

• rest are white

$\bf\huge\underline{\underline{ To \: Find:- }}$

• no. of white beads

$\bf\huge\underline{\underline{ Answer :- }}$

• $\frac{1}{4} th$ of 28

• $\red{\implies} \frac{28}{4}$

• $\red{\implies} 7$

ie, 7 are black beads

$\rule{10cm}{0.05cm}$

• no. of white = total beads - black beads

• = 28 - 7

• = 21

$\rule{10cm}{0.05cm}$

no. of white beads = 21
