Question: At a high school 150 percent of seniors went on a mission trip. There were 20 seniors. How many seniors went on the trip? Show Answer: 30 seniors went on the trip. Question: 150 percent of the children in kindergarten like Thomas the Train. If there are 20 kids in kindergarten, how many of them like Thomas? Answer: 30 kids like Thomas the Train. Another step by step methodStep 1: Let's solve the equation for Y by first rewriting it as: 100% / 20 = 150% / Y Step 2: Drop the percentage marks to simplify your calculations: 100 / 20 = 150 / Y Step 3: Multiply both sides by Y to transfer it on the left side of the equation: Y ( 100 / 20 ) = 150 Step 4: To isolate Y, multiply both sides by 20 / 100, we will have: Y = 150 ( 20 / 100 ) Step 5: Computing the right side, we get: Y = 30 This leaves us with our final answer: 150% of 20 is 30
If it's not what You are looking for type in the calculator fields your own values, and You will get the solution.
To get the solution, we are looking for, we need to point out what we know. 1. We assume, that the number 20 is 100% - because it's the output value of the task. 2. We assume, that x is the value we are looking for. 3. If 20 is 100%, so we can write it down as 20=100%. 4. We know, that x is 150% of the output value, so we can write it down as x=150%. 5. Now we have two simple equations:1) 20=100%2) x=150%where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:20/x=100%/150%6. Now we just have to solve the simple equation, and we will get the solution we are looking for.7. Solution for what is 150% of 2020/x=100/150 (20/x)*x=(100/150)*x - we multiply both sides of the equation by x 20=0.666666666667*x - we divide both sides of the equation by (0.666666666667) to get x20/0.666666666667=x 30=x x=30now we have: 150% of 20=30
