Jasper's lawn is 3/4 of an acre in size. The fertilizer bag states that 5 1/2 bags are required for 1 acre. How many bags does Jasper need to fertilize his lawn?

Sagot :

Answer: [tex]4\dfrac{1}{8}\ \text{bags}[/tex]

Step-by-step explanation:

Given

Jasper lawn is three-fourth of an acre

1 acre of land requires [tex]5\frac{1}{2}[/tex] bags

convert mixed numeral to fraction

[tex]\Rightarrow 5\dfrac{1}{2}=\dfrac{11}{2}[/tex]

[tex]\therefore 1\ \text{acre}\equiv\dfrac{11}{2}\ \text{bags}\\\\\Rightarrow \dfrac{3}{4}\ \text{acre}\equiv \dfrac{11}{2}\times \dfrac{3}{4}=\dfrac{33}{8}\ \text{bags}[/tex]

[tex]\Rightarrow \dfrac{33}{8}\ \text{bags}=4\dfrac{1}{8}\ \text{bags}[/tex]
