Answer:
Simplify
1. 20:10 = 2:1
2. 30:36 = 5:6
3. 54: 12 = 18:7
Step-by-step explanation:
Answer for Number 1
The GCF of 20 and 10 is 10
Divide both by the GCF, 10:
20 ÷ 10 = 2
10 ÷ 10 = 1
The ratio 20 : 10 can be reduced t by dividing both terms by the GCF = 10
20 : 10 = 2 : 1
You know that d = 100 and w = 125, so you plug that into the equation and solve as shown:
b= 100 + d - w
= 100 + 100 - 125
= 200 - 125
= $75
You now have $75 left as balance.
