Step-by-step explanation:
To solve problems like these, first make a common denominator. Then add/subtract. Finally, simplify.
a. 4/9+14/27=12/27+14/27=26/27
b. 3/10+1/2=3/10+5/10=8/10=4/5
c. 1/10+11/40=4/40+11/40=15/40=3/8
d. 1/16+3/8=1/16+6/16=7/16
a. 7/9-1/3=7/9-3/9=4/9
b. 3/4-3/20=15/20-3/20=12/20=3/5
c. 11/24-1/6=11/24-4/24=7/24
d. 9/14-3/7=9/14-6/14=3/14
Please give me Brainliest because I worked very hard on these. I hope you understand the concept better now and happy mathing!
