Noah buys a packet of beads. He uses 1/2 of the packets to make a necklace, and 2/5 of the packet to make a bracelet. What fraction of the packet is left over
I think there is information that is not included here. First you would do 1/2+2/5 which is .9 but we don’t know the overall number of the packet. if we did, it would be the overall number of the packet - .9 but this might be a trick question so i would just put .9
