One way is to make into fracitons and simplify
A.5/7=25/35?
yes, true
B. 6/9=18/36?
no
C. 9/18=16/36?
no
D. 35/120=75/250?
no
another way is
if a/b=c/d, then (ad)/(bc)=1 or ad=bc
A is answer
For example: if you chose to invite 10 people the skating rink would cost a total of $50 including the room fee
If you invite 10 people to the bowling alley you would spend $65 Including the room
The answer would be to choose the skating rink
Step-by-step explanation:
ratio will be
30/27
= 10/9
=10:9
<span>22% when expressed as a fraction is 22/100.
to write this in the simplest form, we have to keep dividing both numerator and denominator by a common number.
22/100 , both are divisible by 2. therefore when 22/100 is divided by 2
</span>

<span>
then we get 11/50. this cannot be divided any further by a common factor to both. therefore simplest form is 11/50</span>
