80%
40%
12%
8%

Answers

Your answer would be 12%. This is because the 'and' rule for probability, the one that is used when we want to determine P(A) and P(B), is to multiply. This means we can convert both percentages to decimals, which gives us 0.6 and 0.2, and then multiply them to get 0.12 as our probability. 0.12 as a percentage is 12%, so that is your answer.
I hope this helps!

Heather is trying to decrease the amount of toys that Oliver has. Originally, he had 55 toys in his room and now he only has 30. By what percentage did Heather decrease the amount of toys?

Answers

Answer:  45.45%

Step-by-step explanation:

Given:  The number of toys in Heather's room before = 55

The number of toys now in the room = 30

Now, the decrease in the toys = 55-30=25

We know that the percent decrease is given by ;-

\frac{\text{Decrease in amount}}{\text{amount before}}*100

\n=(25)/(55)*100=45.4545\approx45.45\%

Hence, Heather decrease the amount of toys by  45.45% .
25/55 = x/100, so I think it is 45% Decreased.

How do you make nine fourths a equliavent fraction

Answers

9/4 --> 

See how many times 4 goes into 9. Then take the leftover and put it over the denominator. 

So, 4 goes into 9 twice, to get 8. 
With 1 leftover, you put it over the denominator, 4. 

So, you get: 2 and 1/4
In other words, you would be putting your final answer into a mixed fraction.

You would divide 9 by 4

4 goes into 9 twice..., 4x2=8.

9-8=1

Use the remainder and divisor to write your fraction part and 2 as your whole number.

Answer: 2 1/4
