Answer:
(a) 5/14
(b) 54 beads
(c) 6 green beads
Step-by-step explanation:
(a) Find the total number of units for red and green beads.
5 + 9 = 14
Since red beads is 5, it is 5/14.
(b) Find the units for red and green beads altogether.
5 + 9 = 14
14 units = 84 beads
Find one unit.
1 unit = 84 ÷ 14 = 6 beads
Since green beads have 9 units, find how many beads there are in 9 units.
9 units = 6 x 9 = 54 beads
(c) As there are 54 green beads and Susie wants to have twice as much green beads as red beads, she have to find how many red beads there are first.
Since red beads have 5 units, find how many beads there are in 5 units.
5 units = 6 x 5 = 30 beads
After that, since she wants twice, she have to find x2 of 30 beads which are red.
30 x 2 = 60
After that, find the remaining amount of green beads needing to make x2 of 30.
60 - 54 = 6 beads (green)
