27 3/10 - 12 5/9 write in old style math

- 15

Step-by-step explanation:

We need to make and have the same denominator, or bottom half, before we can subtract them.In order to do this, we need to find a number that both 10 and 9 (the bottom numbers) both go into. (Hint! Multiplying them together usually helps!)This number is 90. (See? 10 • 9 = 90!)Since we multiplied 10 by 9 to get 90, we need to multiply the top (3) by 9 too, to get us .We multiply by 10 to get us .Now we can subtract 27 and 12 .27 - 12 = 15 (big numbers)27 - 50 = -23 (fractions)Now we have - 15

If I am incorrect in my reasoning, please let me know so that I can plan better for my future answers. Have an amazing day.

2.4+3.2t. you get the answer by adding the ones with variables and ones without
