Answer:
[tex]The\ number\ of\ serving\ of\ \frac{3}{4}\ size\ are\ 24 .[/tex]
Step-by-step explanation:
As given
[tex]There\ are\ 18\ cupcakes\ and\ serving\ size\ is\ \frac{3}{4} .[/tex]
[tex]Let\ us\ assume\ that\ the\ numbers\ of\ \frac{3}{4}\ sizes\ serving\ be\ x.[/tex]
Equation becomes
[tex]\frac{3}{4}\times x = 18[/tex]
simplify the above
[tex]\frac{3x}{4} = 18[/tex]
[tex]\frac{4\times 18}{3} =x[/tex]
x = 6 × 4
x = 24
[tex]Therefore\ the\ number\ of\ serving\ of\ \frac{3}{4}\ size\ are\ 24 .[/tex]
