7. What's the sum of 2/5 and 2/4?

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 :)

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.

8

step-by-step explanation:

to find the amount of gift bags to use all the supplies, find the gcf or greatest common factor. this is the largest number which multiplies evenly into each term.

48 has factors: 1, 2, 3, 4, 6, 8, 12. 16, 24, 48

80 has factors: 1, 2, 4, 5, 8, 10, 16, 20, 40, 80

64 has factors: 1, 2, 4, 8, 8, 16, 32, 64

the highest number factor they all share in common is 8. this means there will be 8 bags with 6 pencils, 10 markers, and 8 stickers in each bag.
