See explanation

Let's break this down word for word:

The quotient of means that there will be some sort of division going on. We can express this $"something"/"something"$ for now.

a number can be a variable and expressed as $n$ . Thus far, we have an expression like this:

$n/"something"$

7 is simply $7$ but the phrase The quotient of a number and 7... can be expressed as

$n/7$

Lastly, is 30. The is is the same as an equal sign. So is 30 gives us:

$=30$

Thus, the entire phrase: The quotient of a number and 7 is 30 can be written as:

$n/7=30$

If we wanted to find this number, we can simply solve for $n$

$7timesn/7=30times7$

$cancel7timesn/cancel7=210$

$n=210$

We can verify this by substituting $210$ for $n$ in the original equation:

$210/7=30$

$30=30larr$ TRUE
