Hi there!
• Covert 1 [tex]\dfrac {1}{2}[/tex] into normal fraction.
Cuz' following quantity, 1 [tex]\dfrac {1}{2}[/tex] is in the form of mixed fraction.
∴ 1 [tex]\dfrac {1}{2}[/tex] = [tex]\dfrac {3}{2}[/tex]
Accr'ding to the question :-
A recipe for one batch calls [tex]\dfrac {3}{2}[/tex] cups of flour.
∵ 1 batch needs = [tex]\dfrac {3}{2}[/tex] cups of flour
Multiply 3 to both th' sides :-
3 × 1 batch needs = 3 × [tex]\dfrac {3}{2}[/tex] cups of flour
∴ 3 batchs needs = [tex]\dfrac {9}{2}[/tex] Or 4 [tex]\dfrac {1}{2}[/tex] cups of flour.
~ Hope it helps!
