3/2 - 6/5 = ?
5 and 8/9 - 1 = ?
15/10 - 12/10 = ?
5 8/9 - 1 = 4 8/9
3/2 - 6/5 = 15/10 - 12/10 = 2/10 = 1/5
5 8/9 - 1 = 4 8/9
no need to worry about the fraction, since the 1 is just subtracted from the 5.
To solve the first equation (3/2 - 6/5), you need to find a common denominator for the fractions. The least common multiple (LCM) of 2 and 5 is 10.
For the first fraction (3/2), you need to multiply both the numerator and denominator by 5 to get the same denominator as the LCM: (3/2) * (5/5) = 15/10.
For the second fraction (6/5), you need to multiply both the numerator and denominator by 2 to get the same denominator as the LCM: (6/5) * (2/2) = 12/10.
Now that both fractions have the same denominator of 10, you can subtract them: 15/10 - 12/10 = (15 - 12)/10 = 3/10.
Therefore, the answer to 3/2 - 6/5 is 3/10.
To solve the second equation (5 and 8/9 - 1), you first need to convert the whole number 5 into fractions with the same denominator as the fraction 8/9.
Since the denominator of 8/9 is 9, you can convert the whole number 5 into a fraction with a denominator of 9: 5 = 45/9.
Now that both numbers have the same denominator, you can subtract them: 45/9 - 1 = (45 - 9)/9 = 36/9.
Simplifying the fraction 36/9, you can divide both the numerator and denominator by their greatest common divisor, which is 9: (36/9) รท (9/9) = 4/1.
Therefore, the answer to 5 and 8/9 - 1 is 4/1.
