Wo numbers are in the ratio of 2 to 3. If the smaller number is 18, the larger number is
Zarrin [17]
The simplified ratio is 2:3. Since the smaller number when it's not simplified is 18, let's divide 18 by 2 to get our factor.
18/2 = 9.
So we can multiply 9 by 3 to get the missing larger number.
9 x 3 = 27.
Your missing number is 27, hope this helps!

1. Solve for x: 3x-3/5+2=5
WINSTONCH [101]

Answer:

x = 6/5

Step-by-step explanation:

3x - 3/5 + 2 = 5

<u>Add 3/5 and -2 on both sides.</u>

3x = 5 + 3/5 - 2

3x = 18/5

<u>Divide 3 on both sides.</u>

x = 18/5 ÷ 3

x = 18/15

x = 6/5
