Hey there! :)
Answer:

Step-by-step explanation:
Convert 1 2/7 to an improper fraction:
1 2/7 --> ![\frac{9}{7}](https://tex.z-dn.net/?f=%5Cfrac%7B9%7D%7B7%7D)
Convert -2 1/4 to an improper fraction:
-2 1/4 --> ![\frac{-9}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B-9%7D%7B4%7D)
Divide by multiplying by the reciprocal:
![\frac{9}{7} * \frac{4}{-9}= \frac{9*4}{7*(-9)}= \frac{-4}{7}](https://tex.z-dn.net/?f=%5Cfrac%7B9%7D%7B7%7D%20%2A%20%5Cfrac%7B4%7D%7B-9%7D%3D%20%5Cfrac%7B9%2A4%7D%7B7%2A%28-9%29%7D%3D%20%5Cfrac%7B-4%7D%7B7%7D)
Therefore, 1 2/7 divided by -2 1/4 equals -4/7.

500/100 but 5/1 is simplified
4.23-2.75
= 4.00 + 0.20 + 0.03 - 2.00 - 0.70 - 0.05
= 2.00 + 0.20 + 0.03 - 0.70 - 0.05
= 2.00 - 0.50 - 0.02
= 1.50 - 0.02
= 1.48
