They are not.

1/2 is a half, while 5:6 is five sixths. 5:6 is greater than a half.

Answer:

$\dfrac{a+b}{a}$

Step-by-step explanation:

There is nothing to solve. Perhaps you want to simplify the expression.

$\dfrac{a^{-1}+b^{-1}}{b^{-1}}=\dfrac{b(a^{-1}+b^{-1})}{b(b^{-1})}=\dfrac{b}{a}+1=\boxed{\dfrac{a+b}{a}}$

_____

The applicable rules of exponents are ...

b^-1 = 1/b

(a^b)(a^c) = a^(b+c)

What is 2*2^3 in expanded form?

katrin2010 [14]

Answer:

Step-by-step explanation:

To solve this question,we will have to understand some symbols in mathematics...

For example,* means ×

/ Means÷

We have so many of them

So back to the question

2*2^3 means 2 multiply by 2 raise to the power of 3

So 2^3 is 8

Therefore,2*8 means 2×8

It equals to 16

Therefore the final answer is 16

I hope you understand it better now

Solve. 2/5p=1 1/3 p= 8/15 p= 2 1/12 p= 3 1/3

blsea [12.9K]

Answer:

$p= 3\frac{1}{3}$

Step-by-step explanation:

$\frac{2p}{5} =1\frac{1}{3}$

$\frac{2p}{5} =\frac{4}{3}$

Use cross multiplication.

$2p*3=5*4$

$6p=20$

Now divide both sides by 6.

$p=\frac{20}{6}$

To make the fraction in it's simplest form divide both sides by 2.

$p=\frac{10}{3}$

Now let us write is as a mixed number.

$p= 3\frac{1}{3}$

Hope this helps :-)

Let me know if you have any other questions :-)
