The correct answer is option 4: (8.\frac{1}{4}).\frac{3}{5}

Step-by-step explanation:

Given expression is:

8.(\frac{1}{4}.\frac{3}{5})

The associative property states that for any three terms that are being multiplied, different order of multiplication (i.e. which two terms are multiplied first) will give the same answer.

Let a,b and c be the three terms

then

a.(b.c) = (a.b).c

So applying the associative property on given expression

8.(\frac{1}{4}.\frac{3}{5}) = (8.\frac{1}{4}).\frac{3}{5}

Hence,

The correct answer is option 4: (8.\frac{1}{4}).\frac{3}{5}

Dovator [93]
It looks like you want to evaluate
.. 8j -k +14
for (j, k) = (0.25, 1).

Put the numbers where the letters are. If you cannot do the math, let your calculator do it.
.. 8*0.25 -1 +14
.. = 2 -1 +14
.. = 1 +14
.. = 15

The value of the expression is 15 at (j, k) = (0.25, 1).

Can you plz help me with this 2.25f+5=13.5f+14​
Aleks [24]

Answer:

F=10

Step-by-step explanation:

Add 13.5 and 14 to get 27.5.

2.25f+5=27.5

Subtract 5 from both sides.

2.25f=27.5−5

Subtract 5 from 27.5 to get 22.5.

2.25f=22.5

Divide both sides by 2.25.

f=  

2.25

22.5

​  

 

Expand  

2.25

22.5

​  

=10 by multiplying both numerator and the denominator by 100.

f=  

225

2250

​  

 

Divide 2250 by 225 to get 10.

f=10
