The ratio of red marbles to blue marbles in a jar is 2 to 5. If there are 35 marbles in the jar, how many red marbles are there?

Question

Do have the right answer: 2:35

Answer 1

no. Start with
ratio of red marbles to blue marbles in a jar is 2 to 5
That is, there are 2x reds and 5x blues.
Now you know that there are 35 in total, so what's next?

Answer 2

2/5:35=14
is this right

Answer 3

no. for every 2 reds, there are 5 blues.
So, reds are only 2/7 of the total.
2/7 * 35 = 10

What you should have done was solve for x:
2x+5x = 35
7x = 35
x = 5
Now, reds = 2x = 10
blues = 5x = 25

Answer 4

The ratio of red marbles to blue marbles in a jar is 2 to 5. If there are 35 blue marbles in the jar, how many red marbles are there?

5 x7 =35
2x7=14 red marbles

is this right

Answer 5

The ratio of red marbles to blue marbles in a jar is 2 to 5. If there are 35 blue marbles in the jar, how many red marbles are there?

5 x7 =35
2x7=14 red marbles

is this right

Answer 6

no, no, no ...
collect a group of 7 marbles: 2 red, 5 blue
How many such groups can you make with 35 marbles?
5, Since 5*7 = 35
So, 5 groups, each with 2 reds and 5 blues.
so, 10 reds and 25 blues
10:25 = 2:5
Why did you not just solve for x as I showd you, and then
red = 2x = 2*5 = 10
blue = 5x = 5*5 = 25
