​

Answer 1

Answer:

$\frac{ - 45}{7}$

Step-by-step explanation:

$\: \: \: \: \: \frac{4}{7} - 7$

$= \frac{4 - 49}{7}$

$= \frac{ - 45}{7}$

Answer 2

Answer:

$\frac{45}{7}$ is the value we get after subtraction -7 from $\frac{-4}{7}$.

Step-by-step explanation:

Explanation:

According to the question, subtract -7 from $\frac{-4}{7}$

In mathematics, subtract -7 from $\frac{-4}{7}$ can be written as $(\frac{-4}{7} )$ - (-7)

• Subtraction - An arithmetic operation called subtraction simulates the process of deleting items from a collection.

• The negative symbol, or, denotes subtraction.

• For example, subtract 100 from 1000.

• This means, 1000 - 100 = 900

Step 1:

We have, to subtract -7 from $\frac{-4}{7}$

⇒ $(\frac{-4}{7} )$ - (-7)

This can be written as, $\frac{-4}{7} - (\frac{-7}{1} )$

Now, we find out the LCM of 7 and 1.

As we know, the acronym LCM means the least common multiple. When you multiply a number by a whole number, you obtain a multiple.

So, the LCM of 7 and 1 is 7

⇒ $\frac{-4}{7} - (\frac{-7}{1} )$

⇒ $\frac{-4 - (-49)}{7}$ = $\frac{-4 + 49}{7}$ = $\frac{45}{7}$

[Where '-' × '-' = +]

Final answer:

Hence, $\frac{45}{7}$ is the value we get after subtraction -7 from $\frac{-4}{7}$.
