Answer:
There are many.
Step-by-step explanation:
When you say proportional, you are looking for a ratio that is equivalent to the ratio given. In your case, there are many so you might need to be more specific. But still, we can help you figure it out.
An easy way to do this would be to scale it down to its simplest form and then move upwards. To find proportional ratios, just multiply denominator and the denominator with the same factor.

That is your ratio in its simplest form. Now we can scale up, I'll show you how to do one completely:

That's the same ratio scaled up by a factor of 2.
---------------------------------------------------------------------------------------

That's the ratio given
---------------------------------------------------------------------------------------

Scaled up by a factor of 4
---------------------------------------------------------------------------------------

Scaled up by a factor of 5.
The list goes on and on.
Answer:
Step-by-step explanation:
7√x-9√x+10√2+√2 = √x ( 7 - 9) +√2 ( 10+1) = - 2√x + 11√2
Answer:
4m +3 marbles does Helena have in all.
Step-by-step explanation:
Here, m represents the marble in each bag.
She put them in 4 bags with m marbles in each bag.
In each bag she have m marbles
then, in 4 bag she have 4m marbles
⇒total number of marbles= 4m
Since, she had 3 marbles left over.
⇒She have total number of marbles = 4m + 3
Therefore, 4m +3 marbles does Helena have in all.
The fraction 91/10 is equivalent1 to 9 1/10.
This fraction is a IMPROPER FRACTION once the absolute value of the top number or numerator (91) is greater than the absolute value of the bottom number or denomintor (10). So, the equivalent fraction is a MIXED NUMBER which is made up of a whole number (9) and proper fraction (1/10).
<span>The fraction 91/10 is equal to 91÷10 and can also be expressed in decimal form as 9.1.</span>
