Answers

Answer: a) 110 b) 92

Step-by-step explanation:

Since we have given that

Percentage of animals not to climbing on furniture = 43%

Percentage of animals not to clawing on furniture = 29%

Percentage of animals not to fighting with other animals training cats = 17%

If the number of cat owners = 255

Number of owners trained their cat not to climb on furniture is given by

(43)/(100)* 255\n\n=0.43* 255\n\n=109.65\approx 110

If the number of cats owners = 316

Number of owners trained their cat not to claw on furniture is given by

(29)/(100)* 316\n\n=0.29* 316\n\n=91.64\approx 92

Hence, a) 110 b) 92
A. 110 owners
B. 92 owners

What is 7/12 as a percent?

Answers

7/12 is 58.33%
How do we change fractions to percents?
The steps are too simple.

First, divide the numerator (the number at the top of the fraction) by the denominator (the number below the fraction).
In the case above, 7 is the numerator and 12 is the denominator.

So, 7 ÷ 12 = 0.58333

Then, multiply the result by 100. 0.5833 x 100= 58.33

Finally, add the percent (%) sign to the result.

Therefore, 7/12 is 58.33%.
