1. In the fraction 11/13, name the dividend when turning the fraction into a division problem. Then, divid and round the quotient to the nearest hundredth.
2. Turn the fraction 819/3 into a division problem, and solve to find the quotient.
To set up an algebraic equation for this problem, let's denote the unknown number as "x".
According to the given information, "seventy-nine less than a number" can be written as "x - 79". And it is stated that this expression is equal to 47.
So, we can write the equation as:
x - 79 = 47
To solve for x, we need to isolate the variable on one side of the equation.
Starting with the equation:
x - 79 = 47
We can add 79 to both sides of the equation to get rid of the -79 on the left side:
x - 79 + 79 = 47 + 79
Simplifying:
x = 126
Therefore, the number we are looking for is 126.
