x=35
How I got the answer:
What is the value of x? Given the following:
6/21 = 10/x
First cross mutiply
6 * x = 6x = 10 * 21
so 6x = 210
Then divide both sides by 6 and you'll get x=35
Proof x = 35:
6 / 21 = 0.285714286,
10 / 35 = 0.285714286, and 0.285714286 = 0.285714286.
These fractions are all equivalent in value: 2/7, 4/14, 6/21, 8/28, 10/35, 12/42, 14/49, and so on.
Yes because 6/21 = 2/7
There are several possible interpretations of the question:(6/7) / (8/21)6 / [7/(8/21)]6 / [(7/8)/21]et ceteraAssuming it is the first of these, (6/7) / (8/21) = (6/7) * (21/8) = (3/7) * (21/4)= (3/1) * (3/4) = 9/4 or 21/4
9/6 = 21/n3/2 = 21/n Since 3 x 7 = 21, then n must be 14 (2 x 7) and we have:3/2 = 21/14 or 9/6 = 21/14.
6/7 + 1/3 You need to find the common denominator 18/21 + 7/21= 25/21= 1 and 4/21
These fractions are all equivalent in value: 2/7, 4/14, 6/21, 8/28, 10/35, 12/42, 14/49, and so on.
The answer is: 5/21 divided by 10/7 = 1/6
It is 2.1 or 21 over 10
7 over 10=7/10 and 5 over 21=5/217/10*5/21= 7*5/10*21= 35/210 which simplifies to: 1/6
The answer for 6.21= 6 (21/100) because 6 is your whole number and 21 cant be over 10 so it has to be 6 (21/100)
58/21
7/10 - 1/6 = 21/30 - 5/30 = 16/30 = 8/15.7/10 - 1/6 = 21/30 - 5/30 = 16/30 = 8/15.7/10 - 1/6 = 21/30 - 5/30 = 16/30 = 8/15.7/10 - 1/6 = 21/30 - 5/30 = 16/30 = 8/15.
6/7 divided by 9/10 is the same, by inversion, as 6/7 * 10/9 60/63 factor out a 3 and cancel it 20/21 -------------simplest form
10 + 6 + 5 = 21 Here is it done in steps: 10+6+5=21 ^ 16 + 5 ^ 21
The answer for the game is 10
They are 6, 10, 14, 15, 21, 22.They are 6, 10, 14, 15, 21, 22.They are 6, 10, 14, 15, 21, 22.They are 6, 10, 14, 15, 21, 22.
21/30 - 5/30 = 16/30 = 8/15
