Mathematics

NISA [10]3 years ago

Step-by-step explanation:

2/5+2/4 (find common denominator)

The common denominator is 20

2/5 is 8/20 (multiply by 4)

2/4 is 10/20 (multiply by 5)

8/20+10/20 is 18/20

If you simplify 18/20 this would by 9/10 if you divide by 2

so the total is 18/20 or 9/10 simplified

Hope this helps!!!!

Have a nice day :)

Answer: 9/10

Step-by-step explanation:

2/5 + 2/4

Multiply the two denominators (4×5)= 20

Divide 5 by 20= 4, then multiply by 2= 8

Divide 4 by 20= 5, multiply by 2= 10

8 +10/20 = 18/20; divide by a common value of 2 to simplify the fraction

18/20=9/10

I hope this helps.
