can you please help me

Answer: 2/3
Step-by-step explanation:
1/4= 3/12 (4 times 3 equals 12 and 1 times 3 is 3)
5/12= 5/12
3/12+5/12=8/12 (3+5=8 and you keep the denominator the same)
8/12=2/3 (simplified)
Answer: Are you trying to make them into a decimal or make a different fraction out of them?
If decimal then 1/4=0.25,
5/12=0.416
1/4 + 5/12= 0.25+0.416=0.666
Another fraction would be
1/4=2/8
5/12=10/24
1/4+5/12=2/8+10/24=2/3
