Chapter Summary

--- PAGE 1 --- ChapterChapter Animal Jumps 1313 Find the hidden numbers. Numbers put in this box get multiplied by a number and come out. (a) Can you guess the multiplier if you see the 4 numbers coming out of the box? (b) Is there more than one possible multiplier? (c) What numbers might have been put inside the box? Share your thoughts in the class. You can also play this game with your friends. The multipliers 1, 2, and 4 that you found above are the factors of the numbers that have come out of the box, that is, 28, 36, 48, and 72. In fact, these are the common factors of all the numbers. The numbers 28, 36, 48, and 72 are multiples of 1, 2 and 4. The product of two or more factors gives a multiple. A number, when arranged in an array, shows the factors of that number. Are there other numbers that are factors of 15? Try to make other arrays for the number 15. 3 × 5 = 15 Factors Multiple Let us make arrays for the number 12. 1 × 12 = 12 2 × 6 = 12 3 × 4 = 12 --- PAG…
