Answer:

Equivalent ratio states that the two ratios that express the same relationship between numbers.

As, we can create equivalent ratios by multiplying or dividing both the numerator and denominator of a given ratio by the same number.

To find the 3 equivalent ratio of 21:56 as follows:

by definition we have;

(1)

\frac{21}{56} \times \frac{2}{2} =\frac{21\times 2}{56 \times 2} =\frac{42}{112}

(2)

\frac{21}{56} \times \frac{3}{3} =\frac{21\times 3}{56 \times 3} =\frac{63}{168}

(3)

\frac{21}{56} \times \frac{4}{4} =\frac{21\times 4}{56 \times 4} =\frac{84}{224}

Therefore, the three equivalent ratios for 21:56 are;

\frac{42}{112} , \frac{63}{168} ,and \frac{84}{224}

There is an infinite number of equivalent ratios for 21:56, but easier ones are:

42:112 (because 21 * 2 = 42 and 56 * 2 = 112)
63:168 (because 21 * 3 = 63 and 56 * 3 = 168)
84:224 (because 21 * 4 = 84 and 56 * 4 = 224)

My name is Ann [436]

Answer:

The correct number of basic operations that exist in mathematics is four (addition, subtraction, multiplication and division) because the definition of an operation is the carrying out of a task by the application of principles and these four operation are arithmetic operations that have precedence rules or order of operations, such that we must first multiply or divide before adding or subtracting

Division is different from simply multiplying by a fraction because in Euclidean division, the result is a quotient and a remainder, which shows that division can yield more than one result while multiplication yields a single result

For subtraction and addition, one of the differences is that subtraction cannot be simply commuted

a - b = -(b - a)

Subtraction is non-associative;

a - b - c when arranged as (a - b) - c and a - (b - c), can yield different results depending on operation order which is unlike addition

Therefore, the four basic operations in mathematics are addition, subtraction, multiplication and division

∠ DFE = 15°

Step-by-step explanation:

The inscribed angle DFE is half the measure of its intercepted arc, that is

∠ DFE = \frac{1}{2} DE = \frac{1}{2} × 30° = 15°
