When you divide something by 3/4, there's no way something can decrease, unless the number is a fraction below 3/4.
Since in Step 2, they divided 27 by 3/4, but ended up with 20 1/4, that means that they got step 2 wrong, because 27 / (3/4) is equal to 27 * 4/3 = 36
(This is because dividing by a fraction is the same thing as multiplying by the reciprocal of the fraction.)
So therefore they got Step 2 wrong.
Work out length of one second by dividing by 525600, then multiply that answer by 8.333. Answer should be 93026473.1507 miles

Step-by-step explanation:
Jenny planned to solve 2/3 of homework
On Saturday she solved 28 problems, which is 7/8 of the planned number
<u>Planned number is:</u>
- 28 : 7/8 = 28 * 8/7 = 32 problems
<u>Jenny's homework was:</u>
- 32 : 2/3 = 32 * 3/2 = 48 problems
Answer: 
<u>Step-by-step explanation:</u>
Perimeter is the sum of the sides.
The length of AB is 3. The length of AC is 6. The length of BC can be found by using the Pythagorean Theorem: a² + b² = c²
3² + 6² = BC²
9 + 36 = BC²
45 = BC²
√45 = BC
3√5 = BC
Perimeter = AB + AC + BC
= 3 + 6 + 3√5
= 9 + 3√5
Answer:
<h3>1/4</h3>
Step-by-step explanation:
Given
amount of salamanders, = 5
amount of crayfish = 3
amount of minnows = 12
Total fish = Total outcome = 5+3+12
Total outcome = 20
Since we are looking for the probability of selecting salamanders, our expected outcome will be 5.
Probability = expected outcome/total outcome
Pr( salamanders,) = 5/20
Pr( salamanders) = 1/4
Hence the probability of selecting salamanders, is 1/4
