Answer: 5

Step-by-step explanation:

Since, According to the BODMAS, when we solve an expression,

We follow the following sequence,

1. Bracket/ parenthesis

2. Of

3. Division

4.Multiplication

5. Addition

6. Subtraction

Here, the given expression is,

$2 + 3\times 16 - 2\times 21 - 3$

Thus, solving the given expression by following the BODMAS,

We get,

Step 1. $2 + 48 - 42 - 3$

Step 2. $50 - 42 - 3$

Step 3. $8-3$

Step 4. 5

7 times what equals 1?

Arturiano [62]

For this case, the first thing we must do is define a variable.
We have then:
x: unknown number
Doing the multiplication we have:
$(7) (x) = 1
$
From here, we clear the value of x.
We have then:
$x = \frac{1}{7} 
$
Therefore, we have:
$(7) ( \frac{1}{7} ) = 1
$
Answer:
7 times 1/7 equals 1
