Compare Unlike denominators

Compare Unlike denominators. Step 1. Compute the fraction from last year. 25 Fish over 1 foot long. Step 1. Total number of fish caught was 125. Step 1. Our Fraction is:. 25 125. Step 2. Reduce the fraction. 25 and 125 can be divided by 25. 25÷25 = 1. 1 5. =. 125 ÷25 = 5.

  1. Compare Unlike denominators

  2. Step 1 Compute the fraction from last year. 25 Fish over 1 foot long.

  3. Step 1 Total number of fish caught was 125

  4. Step 1 Our Fraction is: 25 125

  5. Step 2 Reduce the fraction • 25 and 125 can be divided by 25 25÷25 = 1 1 5 = 125 ÷25 = 5

  6. Step 3 Compute the fraction from this fishing trip • Find the fraction of fish over 1 foot long that you caught this year. 14 40 Over 1 foot long

  7. Step 4 14 40 Reduce the Fraction 2 • 14 and 40 can be divided by…. 14 ÷ 2= 7 7 20 = 40 ÷ 2= 20

  8. Step 5 Compare the fractions Which is greater? 1 Or 7 5 20 Find the Least Common Multiple

  9. What is a multiple? Multiples of a number = the numbers you get when you multiply it by other numbers. For example: 8,16, 24, 32, are all multiples of 8

  10. Common Multiple When 2 numbers have a common multiple it means that the same number is multiple of both of them

  11. Least Common Multiple: The lowest number that is a common multiple

  12. Going back to the fish problem… 1 Or 7 5 20 Find the least common multiple of 5 and 20

  13. The least common multiple is: 20

  14. Multiply the denominator, 5, to equal 20 • What you do to the bottom number, • you do to the top number equally.

  15. And then we changed our fraction 1/5…
