Question

In a box of 720 pens,40% of the pens are blue. how many blue pens are there in the box?

Answer 1

Answer:

$\huge{ \fbox{ \sf{288}}}$

Step-by-step explanation:

$\star{ \text{ \: Given \: : }}$

$\hookrightarrow{ \sf{Total \: number \: of \: pens \: = \: 720}}$

$\hookrightarrow{ \sf{Percentage \: of \: pens \: that \: are \: blue \: in \: colour \: : 40\% \: }}$

$\star{ \text{ \: To \: find \: \sf: Total \: number \: of \: blue \: pens}}$

$\mathfrak{Let's \: solve} :$

$\mapsto{ \sf{ \:40 \: \% \: of \: 720}}$

$\text{Step \: 1 \: : }$ Convert percentage into fraction.

To convert the percent into a fraction, divide it by 100 and remove the % symbol.

$\mapsto{ \sf{ \frac{40}{100} \times 720}}$

$\text{Step \: 2 \: : }$ 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.

$\mapsto{ \sf{ \frac{40 \times 720}{100} }}$

$\mapsto{ \sf{ \frac{28800}{100} }}$

$\mapsto{ \sf{ \frac{288 \cancel{00} }{1 \cancel{00}} }}$

$\mapsto{ \sf{288}}$

There are 288 blue pens in the box.

Hope I helped!
