The number can be divided by 2 and 3 1980 1980 can be divided evenly by 2 and 3; therefore, it is divisible by 6. Always try dividing by numerator. Example: In 51 17 , both numerator and denominator can be divided by 17.

## How do you solve fractions examples?

For example, to solve 1/2 ÷ 1/6, flip 1/6 upside down so it becomes 6/1. Then just multiply 1 x 6 to find the numerator (which is 6) and 2 x 1 to find the denominator (which is 2). So, the answer is 6/2 which is equal to 3.

## How do you solve a work rate question?

Solution to Problem 1:

1. The work done by Linda alone is given by. t × (1 / 2)
2. When the two work together, their work will be added. Hence. t × (1 / 1.5) + t * (1 / 2) = 1.
3. Multiply all terms by 6. 6 (t × (1 / 1.5) + t × (1 / 2) ) = 6.
4. and simplify. 4 t + 3 t = 6.
5. Solve for t. t = 6 / 7 hours = 51.5 minutes.
