$\huge \boxed{\mathfrak{Question} \downarrow}$

Evaluate the expression when c = 21 and d = 4, c - 5d = ?

$\large \boxed{\mathfrak{Answer \: with \: Explanation} \downarrow}$

Given,

c = 21
d = 4
c - 5d = ?

Let's solve it now :-

$\sf \: c - 5d \\ \\ \sf \: Substitute \: the \: values \: of \: c \: and \: d \\ \\ \sf c - 5d \\ \rightarrow \sf(21) - 5(4) \\ \sf \rightarrow21 - 20 \\ = \boxed{\boxed{\bf \: 1}}$

What type of number can be written as an a fraction a/b where a and b are Integres and b is not equal to zero?

faltersainse [42]

Answer:

Integers, Terminating Decimals, Recurring Decimals, Proper and Improper Fractions.

Step-by-step explanation:

The following subset of the real number system can be written in the form $\dfrac{a}{b}$ , b≠0.

Integers(ℤ): These are positive and negative whole numbers. For example, 5 can be written as $\dfrac{5}{1}$

Terminating Decimals: These are fractions that when converted to decimal numbers have an end.

e.g. $\dfrac{5}{2}=2.5$

Recurring Decimals: These are fractions that when converted to decimal numbers do not have an end.

e.g. $\dfrac{8}{11}=0.727272...=0.\overline{72}$

Proper Fractions: These are fractions of the form $\dfrac{a}{b}$ where a<b. An examples is $\dfrac{4}{5}$

Improper Fractions: These are fractions of the form $\dfrac{a}{b}$ where a>b. An examples is $\dfrac{5}{4}$
