1. Change the fraction 3/5 to an equivalent fraction with a denominator of 55.

2. Mandy, a park mechanic, can usually repair a ride in 2 1/2 hours. How many repairs can she make in a 40-hour work week?

3. Rewrite this fraction as a decimal. Divide until the remainder is zero, or the digits in the answer begin to repeat at regular intervals. If you come up with a repeating decimal, write the repeating part three times and add three dots to the end, like this: 1.545454...
....13/40

4. Rewrite this fraction as a decimal. Divide until the remainder is zero, or the digits in the answer begin to repeat at regular intervals. If you come up with a repeating decimal, write the repeating part three times and add three dots to the end, like this: 1.545454...

...17/75

2. child's homework.

1. a denominator is the both number in a fraction. 5 times what number equals 55? multiply 3 by that number, and that's what you put in your numerator of your new fraction!

2. well, let's set up fractions! instead of miles per hour, let's do rides per hour! so, we have 1 ride/2.5 hours. then we have x rides/40 hours. now we just set them equal. so:
1/2.5 = x/40
40 = 2.5x
x = 16
16 rides repaired in 40 hours.

i don't know how to insert long division into html or i'd help you with the next two also. it's just long division, though. you can probably google examples and base yours off that.

3. sol

please use a calculator for obtaining the solutions to the last two of them (divide the numerator by the denominator)
