Answer:
Step-by-step explanation:
Question 1. 50% of what number is 100?
Number = x
50%x = 100
5x/10 = 100 (50% = 2/10)
5x = 1000 (Multiplying by 10 at both sides of the equation)
x = 200 (Dividing by 5 at both sides of the equation)
Part 50 Whole 100 Part 75 Whole 150 Part 100 Whole 200
Question 2. 25% of what number is 30?
Number = x
25%x = 30
x/4 = 30 (25% = 1/4)
x = 120 (Multiplying by 4 at both sides of the equation)
Part 25 Whole 30 Part 50 Whole 60 Part 75 Whole 90 Part 100 Whole 120
Question 3. What did you differently to find the whole using a ratio table?
Using a ratio table is a much more simple path to get the whole. I take it and just calculate the double of the information given to me for completing the next values in my table, until I get the part 100 and its correspondent whole.
