Lynna [10]

Answer:

Step-by-step explanation:

For this problem, you would use the GCF

Find the GCF of 45, 81, 63

GCF(45, 81, 63) = 9

45 = 9 * 5

81 = 9 *9

63= 9 * 7

Since 5, 9, 7 have no common factors, the GCF has to be 9.

This means that the greatest number of plants he can put in each row is 9.

The number of rows he uses for each plant will (obviously) vary.

ddd [48]

Answer: The puppy was $2.25\ lb$ havier in October that it was in September.

Step-by-step explanation:

You need to make the conversion from mixed numbers to decimal numbers. To do it, divide the numerator of the fraction by the denominator add the result to whole part number:

$9\frac{1}{4}=9+0.25=9.25\\\\11\frac{1}{2}=11+0.5=11.5$

The weight of the puppy in September was:

$w_1=9.25\ lb$

And its weight in October was:

$w_2=11.5\ lb$

Subtract its weight in September from its weight in October in order to find how much heavier the puppy was in October than it was in September:

$w_2-w_1=11.5\ lb-9.25\ lb=2.25\ lb$
