Answer:
Step-by-step explanation:
1. The given equation is:
[tex]\frac{3}{5}{\times}\frac{4}{5}[/tex]
Multiplying both the terms, we get
[tex]\frac{12}{25}[/tex]
Option A is correct.
2. The given equation is:
[tex]2\frac{1}{3}{\times}\frac{3}{4}[/tex]
Converting the improper fraction into the mixed fraction,
[tex]\frac{7}{3}{\times}\frac{3}{4}[/tex]
=[tex]\frac{7}{4}[/tex]
Option C is correct.
3. The given equation is:
[tex]\frac{3}{16}{\times}\frac{4}{21}[/tex]
Multiplying both the terms, we get
=[tex]\frac{1}{28}[/tex]
4. The given equation is:
[tex]3\frac{8}{9}{\times}4\frac{4}{5}[/tex]
Converting the improper fraction into the mixed fraction,
[tex]\frac{35}{9}{\times}\frac{24}{5}[/tex]
=[tex]\frac{56}{3}[/tex]
5. One package contains= [tex]5\frac{1}{4}=\frac{21}{4}[/tex] pounds of raisins.
[tex]4\frac{2}{3}[/tex] packages contains=[tex]4\frac{2}{3}{\times}5\frac{1}{4}[/tex] pounds of raisins.
=[tex]\frac{14}{3}{\times}\frac{21}{4}[/tex]
=[tex]\frac{49}{2}[/tex]
Therefore, the baker used [tex]\frac{49}{2}[/tex] pounds of raisins.
