what is the rate of percentage of 4 and base of 80
[tex] \red{r = \frac{4}{80} \times 100}[/tex]
[tex]r = \frac{4}{4} \times 5[/tex]
[tex]r = \frac{20}{4} [/tex]
[tex] \green{r = \boxed{5\%}}[/tex]
1.
[tex] \green{p = 80 \times 5\%}[/tex]
[tex]p = 80 \times \frac{5}{100} [/tex]
[tex]p = 4 \times \frac{5}{5} [/tex]
[tex]p = \frac{20}{5} [/tex]
[tex] \red{p = \underline{4}}[/tex]
2.
[tex] \green{b = 4 \div 5\%}[/tex]
[tex]b = 4 \div \frac{5}{100} [/tex]
[tex]b = 4 \times \frac{100}{5} [/tex]
[tex]b = \frac{400}{5} [/tex]
[tex] \red{b = \underline{80}}[/tex]
[tex] \purple{ \boxed{ \boxed{5\%}}}[/tex]
To find the percentage:
[tex] \orange{p = b \times r}[/tex]
To find the base:
[tex] \orange{b = p \div r}[/tex]
To find the rate:
[tex] \orange{r = \frac{p}{b} \times 100}[/tex]
