I think the answer might be 3/10?
you might just be right.
3 1/15 - 3 11/30
Let's convert these into improper fractions:
46/15 - 101/30
Now we want a comman denominator:
(46 x 2)/(15 x 2) - 101/30
92/30 - 101/30
Now we can subtract the top numbers and keep the denominator:
-9/30
Now let's simply by dividing by 3:
-3/10
Sure, I can help you with that math problem!
To subtract mixed numbers like 3 1/15 and 3 11/30, you need to convert them into improper fractions first.
For 3 1/15, you multiply the whole number (3) by the denominator (15), then add the numerator (1). This gives you (3 * 15) + 1 = 46. So, 3 1/15 can be written as the improper fraction 46/15.
Similarly, for 3 11/30, the improper fraction is (3 * 30) + 11 = 101/30.
Now, let's subtract the two fractions:
(46/15) - (101/30)
To subtract fractions, you need a common denominator. In this case, the least common multiple (LCM) of 15 and 30 is 30. So, we can rewrite the fractions with a common denominator of 30:
(46/15) - (101/30) = (46/15) * (2/2) - (101/30) * (1/1)
= (92/30) - (101/30)
Now, you can subtract the fractions: 92/30 - 101/30 = (92 - 101)/30
So, the result is -9/30, which can be simplified to -3/10.
Therefore, the answer to the math problem 3 1/15 - 3 11/30 is -3/10.
