$2\dfrac{1}{4} -3\dfrac{3}{8}=-\Big(3\dfrac{3}{8}-2\dfrac{2}{8}\Big)=-\Big(2\dfrac{11}{8}-2\dfrac{2}{8}\Big)=\Big(\dfrac{11}{8}-\dfrac{2}{8}\Big)=-\dfrac{9}{8}=-1\dfrac{1}8}=-1,125$

Answer 3

To subtract the mixed numbers 2 1/4 and 3 3/8, you need to convert them to improper fractions and then subtract them. Here's how you can do it:

2 1/4 = (2 * 4 + 1) / 4 = 9/4 3 3/8 = (3 * 8 + 3) / 8 = 27/8

Now, subtract the fractions:

9/4 - 27/8

To subtract fractions, you need to find a common denominator. The least common multiple (LCM) of 4 and 8 is 8. So, we'll convert both fractions to have a denominator of 8:

(9/4) * (2/2) = 18/8 27/8 - 18/8 = 9/8

Therefore, the result of 2 1/4 - 3 3/8 is 9/8.
