Write a division equation that can be solved by multiplying each side by <img src="https://tex.z-dn.net/?f=%20%5Cfrac%7B9%7D%7B

sveta [45]

For example:
(4/9) x=8

Now can solve this equation multiplying each side by 9/4.

(9/4)(4/9)x=(9/4)8
x=18

To check:
(4/9)(18)=(4*18)/9=72/9=8

Simplify the following expression. 3 2/5x3(-7/5)

Studentka2010 [4]

The simplified expression of 32/5 x 3(-7/5) is -672/25

<h3>How to simplify the expression?</h3>

The mathematical expression is given as:

32/5 x 3(-7/5)

Evaluate the product of 3 and -7/5

32/5 x 3(-7/5) = 32/5 x -21/5

Evaluate the product of 32 and -21

32/5 x 3(-7/5) = 672/5 x -1/5

Evaluate the product of 5 and 5

32/5 x 3(-7/5) = 672/25 x -1

So, we have:

32/5 x 3(-7/5) = -672/25

Hence, the simplified expression of 32/5 x 3(-7/5) is -672/25

Calculate the product
14 $\sqrt{(54 - 2) X 6}$
Subtract the numbers
14 $\sqrt{56 x 6}$
Simplify the radical
14 x 2 $\sqrt{13 x 6}$
Multiply the numbers
14 x 2√78
Finally,, calculate the product for your final answer
28√78
