Answer:
4:7
20 divided by 4 = 5
So 5X7= 35.
There are now 35 girls in the club.
New ratio: 20:35
Simplify it.
The simplest form of 20/35 is 4/7.
This IS NOT A TYPO. This IS NOT INCORRECT.
Since we multiplied by 5, and both 20 and 35 are divisible by 5, is will always be 4/7 if you multiply it by 5 in simplest terms.
One more boy joins.
Now the ratio is 5/7.
5/7 cannot be simplified, therefore, 5/7 simplified is 5/7.
Hope this helps!!
