Answer:
[tex] \huge{ \fbox{ \sf{288}}}[/tex]
Step-by-step explanation:
[tex] \star{ \text{ \: Given \: : }}[/tex]
[tex] \hookrightarrow{ \sf{Total \: number \: of \: pens \: = \: 720}}[/tex]
[tex] \hookrightarrow{ \sf{Percentage \: of \: pens \: that \: are \: blue \: in \: colour \: : 40\% \: }}[/tex]
[tex] \star{ \text{ \: To \: find \: \sf: Total \: number \: of \: blue \: pens}}[/tex]
[tex] \mathfrak{Let's \: solve} : [/tex]
[tex] \mapsto{ \sf{ \:40 \: \% \: of \: 720}}[/tex]
[tex] \text{Step \: 1 \: : }[/tex] Convert percentage into fraction.
To convert the percent into a fraction, divide it by 100 and remove the % symbol.
[tex] \mapsto{ \sf{ \frac{40}{100} \times 720}}[/tex]
[tex] \text{Step \: 2 \: : }[/tex] Multiply
To multiply one fraction by another, multiply the numerators for the numerator , and multiply the denominators for its denominator and reduce the fraction obtained after multiplication into lowest term.
[tex] \mapsto{ \sf{ \frac{40 \times 720}{100} }}[/tex]
[tex] \mapsto{ \sf{ \frac{28800}{100} }}[/tex]
[tex] \mapsto{ \sf{ \frac{288 \cancel{00} }{1 \cancel{00}} }}[/tex]
[tex] \mapsto{ \sf{288}}[/tex]
There are 288 blue pens in the box.
Hope I helped!
Best regards! :D
