The answer to this would be 3/8.

you just simplify the given terms, so -1 7/8 can be simplified into -15/8 and 2 1/4 can be simplified into 9/4, add those together to get a sum of 3 over 8 or 3/8.

Good Luck

0.375 ✅

Step-by-step explanation:

- 1 \frac{7}{8}  + 2 \frac{1}{4}  \\  =  -  \frac{15}{8}  +  \frac{9}{4}  \\  =  -  \frac{15}{8}  +  \frac{9 \times 2}{4 \times 2}  \\  =  \frac{ - 15 + 18}{8}  \\  =  \frac{3}{8}  \\  = 0.375
