Jordan is making a beaded necklace two thirds of the beads she uses are red and 4/21 of the beads are blue she wants the rest to be white what fraction of the beads should be white

Respuesta :

Answer:

2/3= 14/21....red beads...4/21 blue beads...14+4= 18/21...so you need 3/21 more to finish the necklace and 3/21=1/7 in white beads

Step-by-step explanation:

2/3 - Red

4/21 - Blue

Change the red fraction so both fractions will have the same denominator

2/3 change to 14/21

Add blue and red together

14/21 + 4/21 = 18/21

Then subtract it from the total to get the white beads

21/21 - 18/21 = 3/21

Simplify it to get 1/7

Ans : 1/7
