Write an expression using the distributive property that can be used to find the quotient 56÷4.

Answers

The quotient of 56 ÷ 4 is 14

Further explanation

Order of Operations in Mathematics follow this following rule :

Parentheses
Exponents
Multiplication and Division
Addition and Subtraction

This rule is known as the PEMDAS method.

In working on a mathematical problem, we first calculate operation that is in parentheses, follow by exponentiation, then multiplication or division, and finally addition or subtraction.

Let us tackle the problem!

This problem is about DIstributive Property.

$( a + b ) * c = ( a * c ) + ( b * c )$

$( a + b ) / c = ( a / c ) + ( b / c )$

Given :

56 ÷ 4 = ?

$56 / 4 = ( 40 + 16 ) / 4$

$56 / 4 = ( 40 / 4 ) + ( 16 / 4 )$

$56 / 4 = ( 10 ) + ( 4 )$

$56 / 4 = \boxed {14}$

Final answer:

The distributive property can be used to simplify the quotient 56÷4 by breaking 56 into 28+28 and then dividing each by four. The resultant expression is 28÷4 + 28÷4 which equals 14.

Explanation:

The question asks for an expression that can be used to find the quotient 56÷4 using the distributive property. This property in mathematics allows you to break down a complex calculations into simpler ones. In this case, we can break 56 into 28+28 and then divide each by 4. So, the expression using the distributive property would be 28÷4 + 28÷4. When you solve this, it simplifies to 7 + 7 which gives the correct quotient of 14, same as 56÷4.
