Answer:  \dfrac{33}{40}\ gm

Step-by-step explanation:

Given

Neville place three weights in the sequence

\dfrac{1}{2}\ gm,\dfrac{1}{5}\ gm,\dfrac{1}{8}\ gm

The total weight of the three weights is

\Rightarrow \dfrac{1}{2}+\dfrac{1}{5}+\dfrac{1}{8}=\dfrac{20+8+5}{40}\\\\\Rightarrow \dfrac{33}{40}\ gm

Thus, herbs weigh  \frac{33}{40}\ gm

How to convert a fraction into a decimal
goldfiish [28.3K]
 If Fraction has denominators such as 10, 100 or 1000 it would be easy to convert it into decimal. Like this:
   6
------- - Fraction.    
 100
Now, Write down the number six and add zeros to it.                   If the denominator has 2 zeros in it then the there should be two decimal numbers. Answer for the above fraction would be: 0.06.

If a fraction does not have denominators such as 10, 100 or 1000, then do the following:

  6
------
 25

The above fraction's denominator is not 10, 100 or 100. So, multiply the numerator and the denominator with a number that would give you the denominator as 10, 100 or 1000.

  6   ×  4  =  24
-----    ----   -------
 25  ×  4  = 100

Now, you can convert it as 0.24

If a fraction has a denominator that cannot be converted into 10, 100 or 1000, then directly divide and write the decimal.

Hope it helped you, Sophia46!!

5^10/5^3 rewrite in the form of 5^n
Sergeeva-Olga [200]

Answer:

5^7

Step-by-step explanation:

To rewrite the expression, you use the laws of exponents.

Using the law of exponents of division, you subtract the exponent of the smaller value (5^3) from the larger value (5^10).

Your expression would now be this:

5^10-3

Since the bases have the same value (5), they remain the same.

As a result of 5^10-3, you would get 5^7 as your answer.

To check that both are equivalent to each other you solve and find the values of both expressions.

5^7=78125

5^10/5^3=78125

5^7=5^10/5^3
