Is 1/4 the answer to this what ratio forms a porportion with 8/36

Flauer [41]

I don't think so. 1/4 and 8/36. 1 times 8 is 8 but 4 times eight is 32 so it would be 8/32.

How do you divide 3/8 by 6/7 in simplest form

Ipatiy [6.2K]

Answer:

7/16

Step-by-step explanation:

First, it is good to know that when you divide fractions, you are multiplying it's reciprocal.

6/7's reciprocal is 7/6, since the reciprocal is $\frac{1}{6/7}$

3/8 / 6/7 =

3/8 * 7/6

Now that we have that, we can just multiply the two:

3/8 * 7/6 =

21/48 =

7/16

Hope this helped :)

Select the correct difference.

scZoUnD [109]

Answer: First option is correct.

Step-by-step explanation:

Since we have given that

$5d^2+4d-3-(2d^2-3d+4)$

We need to find the correct difference.

Collect the like terms together.

$5d^2+4d-3-(2d^2-3d+4)\\\\=5d^2+4d-3-2d^2+3d-4\\\\=5d^2-2d^2+4d+3d-3-4\\\\=3d^2+7d-7$

Hence, First option is correct.

Nataliya [291]

Let x = number of $10 coins.
The total number of coins is 44, therefore there are (44-x) $20 coins.
Total value:
10x + 20(44-x) = 620
-10x + 880 = 620
-10x = -260
x = 26 (number of $10 coins)
44-x = 44-26 = 18 (number of $20 cons)
Answer:
26 $10 coins
18 $20 coins
