For each pair of numbers, tell: By what percent of the first number is the second number larger? By what percent of the second n

snow_lady [41]

Answer:

Part A: 100%
Part B: 50%

Step-by-step explanation:

The difference between 10 and 5 is 5

5 is 100% of 5, so 10 is 100% greater than 5 (part A)

5/5 = 1 = 100%

5 is 50% of 10, so 5 is 50% less than 10 (part B)

5/10 = 1/2 = 50%

Part A is 100%, and Part B is 50%
