21. Which fractions are NOT equivalent?<br> À3/6=2/4<br> -B1/8=1/4<br> C1/3=2/6 D1/4=3/12

ryzh [129]

<h3>Answer: Choice B) 1/8 and 1/4 are not equivalent</h3>

=======================================================

Explanation:

There are two ways to check to see if two fractions are equal.

---------

Method 1) Cross multiplication

3/6 = 2/4

3*4 = 6*2

12 = 12

The last equation is true, so the first equation is true. This shows 3/6 and 2/4 are the same fraction

1/8 = 1/4

1*4 = 8*1

4 = 8

The last equation is false, so 1/8 = 1/4 is false. We found our answer.

1/3 = 2/6

1*6 = 3*2

6 = 6

This equation is true. So we can move on

1/4 = 3/12

1*12 = 4*3

12 = 12

A similar story happens with A and C.

---------

Method 2) Comparing decimal forms

Using a calculator, we can find the decimal form of any fraction

3/6 = 0.5 and 2/4 = 0.5; since we get the same decimal value both times, this means 3/6 = 2/4 is a true statement. Choice A is ruled out.

1/8 = 0.125 and 1/4 = 0.25; we get different decimal values, so we can see that choice B is the answer

1/3 = 0.333.... (the 3s go on forever) and 2/6 = 0.333... we have the same story as choice A, so we can rule out choice C.

1/4 = 0.25 and 3/12 = 0.25, same story as A and C. We can rule out choice D.

The actual width ( w) of a regulation soccer field is 90 meters (m), and the actual length is 120 meters (m). A coach has drawn

vladimir2022 [97]

Answer:

Proportion states that the two equal ratios or fractions are equal.

Use conversion:

1 m = 100 cm

As per the statement:

The actual width ( w) of a regulation soccer field is 90 meters (m), and the actual length is 120 meters (m

⇒Actual length = 120 m and Actual width = 90 m

It is also given that:

A coach has drawn a scale model of the field on a blackboard. If the longest side of his drawing is 18 cm.

⇒ Drawing length = 18 cm = 0.18 m

By definition of proportion:

$\frac{\text{Actual length}}{\text{Actual width}}=\frac{\text{Drawing length}}{\text{Drawing width}}$

Substitute the given values we have;

$\frac{120}{90}=\frac{0.18}{\text{Drawing width}}$

By cross multiply we have;

$120 \cdot \text{Drawing width} = 90 \cdot 0.18$

Simplify:

$120 \cdot \text{Drawing width} =16.2$

Divide both sides by 120 we get;

$\text{Drawing width} =0.135$ m

Or

$\text{Drawing width} =13.5$ cm

Therefore, the other side of the drawing width is 13.5 cm
