Ricardo would swim a farther distance in 1 hour. By taking the number of miles he swam and in the fraction of the hour, you can find the answer.
Divide 5 1/4 by 3 because it took 3/5 of an hour to swim that far. That would lead to 1 3/4 for 1/5 of an hour. Now that we know this, we can multiply 1 3/4 to 5 to get how much he would swim in 1 hour which is 8 3/4
Divide 4 1/2 by 5 because it took 5/9 of an hour to swim that far. That would lead to 9/10 for 1/9 of an hour. Now that we know this, we can multiply 9/10 to 9 to get how much he would swim in 1 hour which is 8 1/10
Since 8 1/10 is less than 8 3/4, Ricardo swam farther

Answer: A multiplicative inverse is what you multiply a number by to get 1.
So, you will need to multiply a number by 1/4 and 1/8 to get one.
The multiplicative inverse of 1/4 is 4 because 1/4 multiplied by 4 is 1.
The multiplicative inverse of 1/8 is 8 because 1/8 multiplied by 8 is 1.
<span>1. Each bike has 2 pedals and 2 wheels;
2. Each tricycle has 2 pedals and 3 wheels;
3. Let x be the number of bikes and, y the number of tricycles;
4. 2x + 3y = 117 and 2x + 2y = 104 => ( </span>2x + 3y ) - ( 2x + 2y ) = 117 - 104 => y = 13 => 2 * x + 2 * 13 = 104 => 2 * x = 104 - 26 => 2 * x = 78 => x = 78 / 2 => x = 39.
