Laden has 7/9 pounds of candy. If he gives 1/4 pound of candy to his friend, what fraction of a pound of candy will he have left?

19/36

Step-by-step explanation:

7/9 - 1/4

The lcm is 36, so we multiply each fraction by 36

(7/9 × 36) - (1/4 × 36)

= (7×4) - (1×9)

=(28-9) / 36

= 19/36

b.) 160 miles on a 5 gallons car

step-by-step explanation:

240/10=24 miles/gallon

160/5=32 miles/gallon

30/1=30 miles/gallon

168/6= 28 miles/gallon

32 miles/gallon is the most amount, so this is the best.
