If he has 9 rows of equal length there are 3 chairs left over.
If he has 7 rows of same length there are 19 left over.
It's important to note that these two setups have the same number of chairs. So we can make an equation out of it.
9x + 3 = 7x +19
2x + 3 = 19
2x = 16
x = 8
So, x (8) is the number of chairs in each row with these setups.
Plug 8 into one of the equations and you will find how many chairs total there are.
9(8) + 3 = 75
There are 75 chairs total
Your answer would be option B
Because multiplied by 4 the ratio would be 16:52
Answer:
0.25
Step-by-step explanation:
It cant become a whole number but it can become a decimal. In order for it to become a whole number such as 1 or 50.0 (you dont have to put the .0 if it has no numbers behind the decimals) you need to have a fraction with the denominator(bottom such as 15/<u>10</u>) smaller than the numerator (top such as <u>15</u>/10) like so 15/10
