What is the formula to find the total time taken to complete a project if a fraction of it is completed in a given time?

Back

If a project is completed in a fraction of the total time, the total time can be calculated using the formula: Total Time = (Time taken) / (Fraction completed).

Front

If Lamont completed 1/8 of his science project in 2/3 of an hour, how do you calculate the total time to complete the project?

Back

Total Time = (2/3) / (1/8) = (2/3) * (8/1) = 16/3 hours = 5 1/3 hours.

Front

How do you calculate the sale price after a discount?

Back

Sale Price = Original Price - (Discount Percentage * Original Price).

Front

What is 12% of $18?

Back

12% of $18 = 0.12 * 18 = $2.16.

Front

If an item costs $18 and is sold at a 12% discount, what is the sale price?

Back

Sale Price = 18 - 2.16 = $15.84.

Front

What is the formula to find the time taken to swim a certain distance at a given speed?

Back

Time = Distance / Speed.

Front

If Ben swam 2/3 of a mile in 4/5 of an hour, how do you find his speed?

Back

Speed = Distance / Time = (2/3) / (4/5) = (2/3) * (5/4) = 10/12 = 5/6 miles per hour.

Front

How do you calculate the time it takes to swim 1 1/2 miles at a speed of 5/6 miles per hour?

Back

Time = Distance / Speed = (1 1/2) / (5/6) = (3/2) * (6/5) = 18/10 = 1 4/5 hours.
