Aspen has 306 green beads and 210 silver beads. For every 5cm of a belt that Aspen sews, they use 40 green beads and 24 silver beads. After how many centimeters of the belt will Aspen have equal numbers of green and silver beads left?□cm
Q. Aspen has 306 green beads and 210 silver beads. For every 5cm of a belt that Aspen sews, they use 40 green beads and 24 silver beads. After how many centimeters of the belt will Aspen have equal numbers of green and silver beads left?□cm
Calculate ratio: Calculate the ratio of green to silver beads used per 5cm of belt.Green to silver ratio = 40 green beads : 24 silver beads.
Simplify ratio: Simplify the ratio to find the smallest whole number ratio.840=5 green beads and 824=3 silver beads.So, the simplified ratio is 5 green beads : 3 silver beads.
Find sets needed: Find out how many sets of beads Aspen can use before running out.Green bead sets = 5306=61.2 sets.Silver bead sets = 3210=70 sets.
Calculate green beads: Since Aspen can't use a fraction of a set, they can use only 61 full sets of green beads.
Calculate silver beads: Calculate the number of silver beads used after 61 sets.Silver beads used = 61 sets ×3 silver beads/set = 183 silver beads.
Calculate silver beads left: Calculate the number of silver beads left after using 61 sets.Silver beads left =210−183=27 beads.
Calculate green beads left: Calculate the number of green beads left after using 61 sets.Green beads left = 306−(61 sets×5 green beads/set)=306−305=1 bead.
