Answer 2

Answer:

• 12% more than 200 = 224
• 10% less than 50 = 45

Step-by-step explanation:

Question:

Find:

• 12% more than 200
• 10% less than 50

Solution:

1) 12% of 200 = $\mathtt{\frac{12}{100}\times200= 24}$

Hence, 12% more than 200 = 200 + (12% of 200)

                                              = 200 + 24 = 224

2) 10% of 50 = $\mathtt{\frac{10}{100}\times50= 5}$

Hence, 10% less than 50 = 50 - (10% of 50)

                                            = 50 - 5 = 45

Extra Information:

• To convert a fraction into a percentage we multiply the fraction by 100.

        Eg - $\frac{3}{4} \rightarrow \big(\frac{3}{4}\times100\big)\% \rightarrow 75\%$

• To write a percentage as a ratio we have to first convert it as a fraction and then write it as a ratio.

        Eg - $19\%\rightarrow \frac{19}{100} \rightarrow 19:100$

• To convert a ratio into percent we first have to convert it as a fraction and then multiply it by 100.

        Eg - $1:2\rightarrow \frac{1}{2} \rightarrow \big(\frac{1}{2}\times100\big)\% \rightarrow 50\%$
