58% is about equal to 60%, or 6 times 10%. 10% of 121 is 12.1.
12.1 * 6 = 72.6
To take this further, 58% is 2% less than 60%, or 2 times 1%. 1% of 121 is 1.21.
72.6  - (1.21 * 2) = 72.6 - 2.42 = 70.18

Answer:

58% of 121 by using 10% is 70.18.

Step-by-step explanation:

Given : 58% of 121.

To find  : estimate 58% of 121 by using 10%.

Solution : We have given  58%

Estimate of  58% is 60%

We need to use 10%

We can write 60%  as 6 times of 10%

Since , 10% of 121

10*\frac{121}{100} =  12.1

60%  =  6 times of 10%

Plugging the values

60%  == 6 times of 12.1

6 *12.1 = 72 .6

To take this further, 58% is 2% less than 60%, or 2 times 1%. 1% of 121 is 1.21.

72.6  - (1.21 * 2) = 72.6 - 2.42 = 70.18

Therefore,  58% of 121 by using 10% is 70.18.

If a class have 32 students and 12 is girls, what is the percentage of girls
Vlad1618 [11]
Hey there! 

Here are the steps involved in answering this question:

1. Write 12 out of 32 as a fraction which is \frac{12}{32}

2. Turn the fraction into a decimal. To do this, divide the numerator by the denominator. The numerator is the top part of the fraction while the denominator is the bottom part of the fraction.

   \frac{12}{32} = 0.375

3.<span> You get 0.375. Now, turn this into a percent. Move the decimal, 2 places to the right or just multiply the decimal by 100.</span>

0.375 = 37.5%

The final answer is 37.5%.
