Answer:
70% of adults do not have allergies.
Step-by-step explanation:
It states that 35 out of 50 adults do not have allergies. If we turn this into a fraction (35/50), we can then multiply the denominator by 2 to make it 100. We would then also multiply the numerator by 2.
35 x 2 =70
70/100 = .7
.7 is just the decimal form of 70%
Note that 5000 is two place values greater than 50. This means that it is 100 times as great as 50.
