Answer:
D.
Step-by-step explanation:
99 multiplied by 1 = 99
99 multiplied by a number less than 1 = less than 99
99 multiplied by a number greater than 1 = greater than 99
In all choices, 99 appears as a factor and is multiplied by a fraction.
If the fraction that 99 is being multiplied by is less than 1, then that product is than 99. If the fraction is equal to 1, then the product is 99. If the fraction is greater than 99, then the product is greater than 99.
Look at the fractions:
A. 20/20 = 1, so 20/20 * 99 = 99
B. 16/15 * 99; 16/15 > 1, so 16/15 * 99 > 99
C. 12/7 * 99; 12/7 > 1, so 12/7 * 99 > 99
D. 10/11 * 99; Since 10/11 < 1, then 10/11 * 99 < 99
D. is the answer because it is the only choice with fraction that is less than 1 multiplying 99.
