Answer:

Step-by-step explanation:

Since tan(x) = sin(x)/cos(x), if sin(x) = cos(x) then tan(x) must be 1.

You can even reason that the acute angle is 45° and sin(x)=cos(x) = $\frac12\sqrt2$ .

The best way to scaffold a grade 2 class to understand the topics such as unitary fractions, fractions in diagrammatic form, write fractions as 1 half is by first explaining the definition then real life application including physical representation.

What is fraction?

A fraction is a portion of a whole or, more roughly, any number of equal pieces. The word fraction comes from the Latin word fractus, which meaning "broken." When expressed in common English, a fraction, such as one-half, eight-fifths, or three-quarters, specifies the number of components of a specific size. A common, vulgar, or simple fraction is one with a non-zero denominator that is displayed below (or after) the line on which the numerator is displayed. Examples of these fractions include 1/2 and 14/3. The uncommon fractions that use numerators and denominators are difficult fractions, compound fractions, and mixed numeral fractions.

Definition or explanation of the topics given in the question:

Unitary fractions or Unit fractions: A fraction with the number one in the numerator is known as a unit fraction in mathematics. Of all the equally sized portions of the whole, it symbolizes one shaded part. "Unit" refers to one.

For instance, 1/4 is the numerical representation of a pizza that has been divided into 4 equal portions, each of which is being consumed by one individual similarly if it got divided between 2 people it is represented as 1/2.

Recognize fractions in diagrammatic form: This could be done by showing the diagrams which contain boxes of two different colors which represents the numerator and denominator.

Write fractions as 1 half: The 1 half fractions are the fractions in which the denominator is twice the the numerator. That is any fraction in the form n\2n where, n = 1, 2, 3, 4.... is the 1 half fraction.

You are drawing a map. Two cities on the map are 7 inches apart. You know the actual distance between them is 1,750 miles. What

Answer:

1 inch : 250 miles
1/15,840,000

Step-by-step explanation:

Map scale factors are usually written a couple of different ways. One of them is the number of miles represented by 1 inch. Here, that is ...

1750 mi/(7 in) = 250 mi/in

Written that way, the scale factor is 1 in : 250 miles.

The other way the scale factor can be written is as a unitless ratio. That ratio is ...

$\dfrac{1\,\text{in}}{250\,\text{mi}}\times\dfrac{1\,\text{mi}}{5280\,\text{ft}}\times\dfrac{1\,\text{ft}}{12\,\text{in}}=\dfrac{1}{250\cdot 5280\cdot 12}=\dfrac{1}{15,840,000}$

The map scale factor is 1 in : 250 miles, or 1/15,840,000.
