Answer and Step-by-step explanation:
First, before you add and solve, you need to make both denominators the same. So, multiply the numerator and denominator of 7/10 by 10 to get: 70/100. Now you should have:
23 + 70
100 100
Simply add the numerators to get 93/100. This cannot be simplified any further, so the final answer is:
93
100
I hope this helps.
