Answer 3

Bigger

Question 4

multiply the numberator of a positive, proper fraction by (3/2)

Answer 4

(3/2) is greater than 1 –> therefore we are incr. the numerator –> fraction value increases!

Question 5

Add 1 to the NUMERATOR of a positive, proper fraction and subtract 1 from its DENOMINATOR..

Answer 5

Numerator increases –> Denominator decreases BUT total value INCREASES… both together incr. value of fraction

Question 6

Answer 6

multiplying both by the same number will NOT change the value of the fractions - stays the same

Answer 7

(3/8) = value betw. 0 and 1, –> decreases value of the number

Question 8

Question 15

1/10 percent of 5000

Answer 15

“1/10 percent” = (1/10)/100 OR easier, 1 percent of 5000 is 50; 1/10 percent is 5 (divide 50 by 10);
remember “x percent” means -> x/100
