Answer:
1. 16:32=1:2
2. 56:200=7:25
Step-by-step explanation:
1. 16:32=1:2 -> both divisible by 8
2. 56:200=7:25 -> both divisible by 8
Answer:
The equivalent ratios are:
s = \frac{LA}{r}s=
r
LA
r = \frac{LA}{s}r=
s
LA
The formula LA = rsLA=rs is given
In order to determine the equivalent ratios, make r the subject of the formula and s the subject of the formula in the above equation
To make s, the subject of the equation, divide both sides of the equation by r
s = \frac{LA}{r}s=
r
LA
To make r, the subject of the equation, divide both sides of the equation by s
r = \frac{LA}{s}r=
s
LA

You need a common denominator while subtracting because really a fraction is a division problem and you cannot do 4/5-8/9 it does not make sense as for multiplication you really just multiplying everything that is why it makes sense.
A- 98+89+123=310 (boys)
A-102+105+117=324 (girls)
B-324-310=14 I found my answer by subtracting the girls from the boys and I got 14
C-They will need to hire 24 more teachers because if you add the students together you will get 644 then you divide it by 20 and you get 32 but since they already have 8 teachers you would just subtract 8 from 32 wich you get 24
