What is 20% of 40, work it out​
Darina [25.2K]

Hey there

Answer:

  • 20% of 40 is <u>8</u><u> </u><u>.</u>

Step-by-step explanation:

In this question we are given a <u>number </u><u>that </u><u>is </u><u>4</u><u>0</u><u> </u><u>.</u> And we have asked to find <u>2</u><u>0</u><u>%</u><u> </u><u>of </u><u>it </u><u>.</u>

<u>Solution</u><u> </u><u>:</u><u> </u><u>-</u>

\longmapsto \qquad \: \: 20\% \times 40

We know that ,

  • Percent ( % ) represent <u>1</u><u>/</u><u>100</u>

<u>S</u><u>o </u><u>,</u>

<u>\longmapsto \qquad \: \: ( 20 \times  \dfrac{1}{100})  \times 40</u>

<u>or </u><u>,</u>

<u>\longmapsto \qquad \: \:  \dfrac{20}{100}  \times 40</u>

Now cancelling zero :

\longmapsto \qquad \: \:  \dfrac{2 \cancel{0}}{1 \cancel{0} \cancel{0}}  \times 4 \cancel{0}

We get ,

\longmapsto \qquad \: \:  2 \times 4

\longmapsto \qquad \: \:     \blue{\underline{\boxed{\frak{8}}}} \quad \bigstar

  • <u>Therefore</u><u> </u><u>,</u><u> </u><u>2</u><u>0</u><u>%</u><u> </u><u>of </u><u>4</u><u>0</u><u> </u><u>is </u><em><u>8</u></em><em><u> </u></em><em><u>.</u></em>
