Problema Solution
Belinda has a bag of beads. She uses 1/3 of the beads to make a bracelet and 3/5 of the beads to make a necklace. She uses 36 more beads to make the necklace. How many beads does Belinda use to make the bracelet?
Answer provided by our tutors
let x = total number of beads used
(1/3)x = the number of beads used for bracelet
(3/5)x = the number of beads used for necklace
she uses 36 more beads to make the necklace
(3/5)x = 36 + (1/3)x
by solving the equation we find
x = 135 beads
(3/5)x = (3/5)*135 = 81 the number of beads used for necklace
