Is 11 1/2 divided by 2 1/4 equals 6 and overestimate or underestimate. Explain

11 1/2 ÷ 2 1/4 is not equal to 6, it is an overestimate.

Step-by-step explanation:

11 1/2 ÷ 2 1/4 = 6

First step: convert the improper fraction to a proper fraction

11 1/2= 23/2

2 1/4= 9/2

The question can be written as:

23/2 ÷ 9/2

=23/2 × 2/9 ( 2 cancels out 2)

= 23/9

=2.56

Therefore, 11 1/2 ÷ 2 1/4 is not equal to 6, it is an over estimate.

I hope this helps.

b) 1/3 * 1/5

step-by-step explanation:

each smallest part is 1/15 since the written one is 1/5 and it's divided by 3 equal parts. (1/5 )/3 = 1/15 = 1/3 * 1/5

$4034.40

the perimeter of the field is the sum of the lengths of the four sides:

47 yd + 158 yd + 47 yd + 158 yd = 410 yd

the cost of 3 ft (1 yd) of fence is 3×$3.28 = $9.84.

so the cost of jake's wood perimeter fance is

(410 yd) × ($9.84 /yd) = $4034.40
