Explain how to find the sum of 3/10 + 4/100

17/50

Step-by-step explanation:

First, to add fractions, we must find a common denominator, in this case, 100.

Then, we must make the fractions being added all have the common denominator.

So, we must multiply 3/10 * 10/10, which equals 30/100

30/100 + 4/100

Then, just add across the numerator to get 34/100, which can be simplified to 17/50

The answer is 17/50

Step-by-step explanation:

Step 1: Find the lowest common factor of 10 and 100

The LCM is 100

Step 2: Divide the LCM  100 by both denominators and multiply there product by there respective numerators.

3(10)/100 + 4/100

30/100 + 4/100

Step 3: Add the numerators together as the denominators are the same

(30 + 4)/100

34/100

Step 5: Divide both numerator and denominator by two

(34/100) ÷ 2

17/50

step-by-step explanation:

u = -(6/7)w

step-by-step explanation:

place all values with 'u' on one side of the equation.

4u + 8w = - 3u + 2w

4u + 3u = 2w - 8w

further simplify the equation by solving the addition and subtraction.

7u = - 6w

make 'u' the independent variable by placing its co-efficient on the right-hand side.

u = - (6/7)w
