Answer: 15 crocodriles

Step-by-step explanation:

We know that the ratio is 4:3

This means that for each 4 hippos, we have 3 cocodriles.

We know that there are 20 hippos.

How many groups of 4 hippos we have?

n = 20/4 = 5

So we have 5 groups of 4 hippos, this means that we also have 5 groups of 3 crocodiles, then we have:

3*5 = 15 crocodiles

How do you convert 0.51 repeating as a fraction
suter [353]
Here are the following factors for 51 and 100:
51= 1, 3, 17, 51
100=1, 2, 4, 5, 10, 20, 25, 50, 100
Since none of the numbers that go into 51 go into 100
(1 doesn't count) 51/100 is the correct answer, and cannot be put into lower terms.

Please help !!!!! Explain to me and need answer quick
schepotkina [342]

Answer:

We can see that the denominators of both the numbers is not same

So in order to make it same for the both numbers, we will multiply the second number by 2/2 ,(which is basically 1 so it won't affect our calculations)

\frac{11}{2^2 * 5^2} - \frac{2}{2^2 * 5^2}

So we will just subtract the numbers now

\frac{9}{2^2 * 5^2} <em>This is the answer </em>

A printing company charges $42 plus $0.05 per page. Another company just charges $0.08 per page. How many pages are in an order
Nookie1986 [14]
There should be 1,400 pages in an order that costs the same for both companies.

Let x be the unknown number of pages.

1st Company = 42 + 0.05x
2nd Company = 0.08x

0.08x = 42 + 0.05x
0.08x - 0.05x = 42
0.03x = 42
0.03x / 0.03 = 42 / 0.03
x = 1400 pages

To check

0.08x = 42 + 0.05x
0.08 (1400) = 42 + (0.05 * 1400)
112 = 42 + 70
112 = 112
