Step-by-step explanation:
The way to find missing numbers in equivalent ratios is to multiply the means (the first denominator and the second numerator) and multiply the extremes (the first numerator and the second denominator). It sounds really complicated, but it is quite simple =)
2/5 = x/10
The means in this equivalent ration are 5 and x. The extremes are 2 and 10.
5x = 20
Now solve =)
x = 4
That was pretty simple. Let's move on to the next one. Do exactly the same thing here:
4/10 = 6/x
60 = 4x
15 = x
That was pretty simple, too! Keep going!
6/15 = x/25
15x = 150
x = 10
All of these should be equal, so check them by dividing:
2/5 = 0.4
4/10 = 0.4
6/15 = 0.4
10/25 = 0.4
They all check out, so these are your answers: 2/5, 4/10, 6/15, 10/25
I really hope this helps you =)
I’m not sure but please tell me where i can watch it

Answer:
4% Hope this helped.
Step-by-step explanation:
The formula is: final value minus starting value divided by the starting value then times 100
THIS FORMULA ONLY APPLIES TO PERCENT INCREASE
<u>Final Value−Starting Value</u>
Starting Value x100
Plug numbers in
2600-2500/2500 x 100
100/2500=0.04
0.04x100
=4%
Answer:
If ab=12 and a2+b2=25 then,
(a+b)2=a2+b2+2ab
a+b=√25+24
a+b=√49
a+b=7
