Happy webbing day The clues
Five spiders named Creeper, Leggy, Spot, Muffy and Fido spun webs that were 48, 36, 24, 18 and 12 centimetres in diameter. Recently, they got together and compared what they had captured in their webs. They caught 900, 850, 700, 450 and 425 flies. They caught 350, 225, 200, 175 and 100 moths. They caught 90, 85, 70, 45 and 30 bees. Based on the clues, match the spiders with their web’s diameter, and the number of flies, moths and bees they caught.
1. The diameter of Fido’s web was the same as the radius of Creeper’s web, the diameter of Creeper’s web was the same as the radius of Spot’s web, and, of course, the radius of Muffy’s web was the same as the diameter of Leggy’s web. 2. Multiply Spot’s bee number by 10 to find Leggy’s fly number, and multiply Leggy’s bee number by 10 to uncover Fido’s fly number. 3. Creeper and Leggy’s combined fly total was 1750, and Muffy and Fido’s combined bee total was 75. 4. Creeper did not catch the most bees, and if you multiplied Muffy’s bee number by 10, the answer would be Spot’s fly number. 5. Creeper and Leggy caught a combined total of 575 moths, and Muffy and Fido caught a combined total of 275 moths. 6. Creeper’s moth number was one-half of Fido’s fly number, and Muffy’s moth number was one-half Spot’s moth number.
