Well, the above statement is true so it is not the associative properties because they are just switched around.
What is being demonstrated is the commutative property of addition.

Answer:

225 seconds

Step-by-step explanation:

150/(2/3) = 150(3/2) = 225

proof:

150 = 2/3

75 = 1/3

225 = whole

Can you use the Associative Properties with subtraction and division? Use (14 - 8) - 2 and 24/(4/2 to explain.

larisa86 [58]

No, you cannot use the Associative properties with either subtraction and division, because it will not end to the same result. 14-8 is not the same as 8-14, and 24/4 is not the same as 4/24, but for example 3+2 is the same as 2+3.

(-3/2x4/5)+(9/5-10/3)-(1/2x3/4)

$\left ( \frac{3}{2}\times \frac{4}{5} \right )+\left ( \frac{9}{5}- \frac{10}{3} \right )-\left ( \frac{1}{2}\times \frac{3}{4} \right )$

In the first parenthesis, multiply the numerators so we get -12 and after multiply the denominator we will get 10

So the fraction in the first parenthesis will be $\left ( \frac{-12}{10} \right )$

To solve the 2nd parenethesis, find the LCD of the denominator.

So the LCD of 5 and 3 = 15,

Now make the each denominator same as that of LCD.

So the new fractions in the 2nd parenthesis = $(\left ( \frac{27}{15}- \frac{50}{15} \right )$ = $\left ( \frac{-23}{15} \right )$

In the third parenthesis, multiply the numerators so we get 3 and after multiply the denominator we will get 8

So third parenthesis = $\left ( \frac{3}{8}\ \right )$

= $\left ( \frac{-12}{10} \right ) + \left ( \frac{-23}{15} \right ) -\left ( \frac{3}{8}\ \right )$

LCD of 12,15 and 8 is 120

= $\left ( \frac{-144}{120} \right ) + \left ( \frac{-184}{120} \right ) -\left ( \frac{45}{120}\ \right )$

= $\left ( \frac{-373}{120} \right )$

The base length for each parallelogram is $1\frac{5}{8}$ yards.

Step-by-step explanation:

Step 1:

The area of a parallelogram is given by the product of its base length and height.

So the parameters needed to determine the area of a parallelogram are its base length and its height.

We must convert the mixed fractions into improper fractions. To do that we multiply the number with the denominator and add with it the numerator whereas the denominator remains the same.

To convert the fraction $3\frac{5}{7} = \frac{(3)(7)+5}{7} = \frac{26}{7}$ which is the area.
