Answer:
31/6 or 5 1/6
Step-by-step explanation:
First, turn 1.5 into a fraction as “fraction answer” means it wants a answer in the form of a fraction.
1.5 as a fraction is 1 1/2
So the equation is:
2 1/3 - 1 1/2
Now, turn the mixed fractions into improper fractions.
2 1/3 becomes 7/3 and 1 1/2 becomes 3/2
Now the equation is
7/3 - 3/2
To subtract fractions you must make the denominator (bottom number) the same number by finding the lowest common multiple.
3 and 2’s Lowest common multiple is 6.
When making the denominator 6 you also multiply the numerator.
3 x 2 = 6 and 7 x 2 = 14
So the first fraction is now: 14/6
Now:
2 x 3 = 6 and 3 x 3 = 9.
The other fraction is now 9/6
Now:
14/6 - 9/ = 5/6
Now:
6 - 5/6
Now turn 6 into a fraction.
6/1 - 5/6
Now turn the 6/1’s denominator into 6
6 x 6 = 36; 1 x 6 = 6
36/6 - 5/6 = 31/6
The answer is 31/6!
