Step-by-step explanation:
3 1/2 ÷ 1/2 = 7
Given:
To bake a cake, [tex]\frac{1}{2}[/tex] cup of water is used with 1 cup of flour.
To Find:
Amount of water to be added with [tex]3\frac{1}{2}[/tex] cups of flour.
Solution:
"By using unitary method, we can find the amount of water to be mixed with [tex]3\frac{1}{2}[/tex] of flour for a cake"
∵ 1 cups of flour requires water = [tex]\frac{1}{2}[/tex] cup
∴ [tex]3\frac{1}{2}[/tex] cups of flour will require water = [tex]\frac{1}{2}\times 3\frac{1}{2}[/tex] cups
= [tex]\frac{1}{2}\times \frac{7}{2}[/tex] cup
= [tex]\frac{7}{4}[/tex] cups
= [tex]1\frac{3}{4}[/tex] cups
Therefore, [tex]1\frac{3}{4}[/tex] cups of water will be mixed with [tex]3\frac{1}{2}[/tex] cups of flour to bake a cake,
