Answer:

Answer (C) ⇒ He replaced the wrong term with its reciprocal in step 2

Answer (A) ⇒ How many 3/8 's in 48

Step-by-step explanation:

∵ The distance = 25 miles

∵ The time = 2/3 hour

∵ Average speed = distance ÷ time

∴ Average speed = 25 ÷ 2/3 ⇒ step 1 (he is √)

                              = 25 × 3/2 ⇒ step 2 (his 1st error 1/25 × 2/3)

                              = 75/2 miles/h

∵ How many 3/8 's are in 48 means:

  48 ÷ 3/8 = 48 × 8/3 = 128

∴ Answer (A) is best modeled with a division expression

Answer:

1. Leona traveled 25 miles in 2/3 of an hour. What was her average speed in miles per hour?

speed = distance/time

So, her speed will be 25/2/3

So, this becomes : 25*3/2

Nate did the wrong calculation here.

Instead of inversing 2/3 , he inversed 25.

So, answer is C-He replaced the wrong term with its reciprocal in step 2.

2. A is right.

How many 3/8 's are in 48?

B is multiplication, C is addition and D is subtraction.

What would 0.1666667 be as a fraction
amm1812
That would be <u><em>1/6</em></u>. To find this, first, move the decimal two places to the right, and put that number over 100:
<u />16.666.../100
This fraction can then be simplified by dividing both sides by 16.666... to get 1/6.
In reality, the fraction 1/6 simply cannot be expressed as a decimal, but many people just put 0.1666666... because it is a pretty good approximation.
Hope this helps!
