Answer:
27.2
Step-by-step explanation:
all you have to do is divide the numerator by the denominator.
Roger is going to invite 12 girls and only 4 boys
Since 16 is divided by four, we can take three groups of four to represent the girls
And one group of four to represent the boys.
E + 10 = P
(P + 5) = 2(E +5)
E = P -10
P + 5 = 2((P-10)+5)
P + 5 = 2P -20 + 10
P + 5 =2P - 10
-P = -15
P = 15
Answer:
2:5
Step-by-step explanation:
We can simplify the ratio 378 : 945 by dividing both terms by the greatest common factor (GCF).
The GCF of 378 and 945 is 189.
Divide both terms by 189.
378 ÷ 189 = 2
945 ÷ 189 = 5
Therefore:
378 : 945 = 2 : 5
