Use a proportion to solve the problem.
On Anne's bicycle, the ratio of pedal turns to rear-wheel turns in second gear is 4 to 7. If her rear wheel turns 994 times per mile, how many times does she turn the pedal in one mile? Express your answer as an integer or mixed number.
I am so bad with ratios. I understand their pupose, I just don't understand how to solve them. Thank you again.
Use a proportion to solve the problem.
On Anne's bicycle, the ratio of pedal turns to rear-wheel turns in second gear is 4 to 7. If her rear wheel turns 896 times per mile, how many times does she turn the pedal in one mile?
To solve this problem using a proportion, we first need to set up the ratio using the given information. The ratio of pedal turns to rear-wheel turns is 4 to 7. This means for every 4 pedal turns, there are 7 rear-wheel turns.
Let's represent the number of pedal turns as "x" and the number of rear-wheel turns as 994. With this information, we can set up a proportion:
4/7 = x/994
To solve for x, we need to cross-multiply and then solve for x:
4 * 994 = 7x
3976 = 7x
To get the value of x, we need to divide both sides of the equation by 7:
3976 / 7 = x
x ≈ 568
Therefore, Anne turns the pedal approximately 568 times in one mile.
4:7 = x:994
4/7 = x/994
x = 4*994/7
x = 568
