Compare numbers using multiplication

πŸ”Ή Multiplication Shows Equal Groups

  • Multiplication means adding equal groups.
  • Example: 3 Γ— 4 = 12 means πŸ‘‰ 4 + 4 + 4 = 12

βš–οΈ Use Multiplication to Compare Two Numbers

  • We check how many times one number fits into another.
  • Example: 20 is 4 times 5 because 5 Γ— 4 = 20 βœ…

πŸ” β€œTimes As Many” Comparison

  • The phrase “times as many” tells how much bigger one number is.
  • Example:
    πŸ§’ Raju has 6 pencils
    πŸ‘¦ Teja has 18 pencils
    β†’ Teja has 3 times as many pencils as Raju (6 Γ— 3 = 18)

πŸ” Use Multiplication to Compare Groups

If both numbers share a common factor, we can compare easily:

  • Example: 8 and 24
  • 8 Γ— 3 = 24 β†’ 24 is 3 times 8

πŸ“‰πŸ“ˆ Smaller to Bigger or Bigger to Smaller

  • To compare smaller to bigger β†’ Multiply
    Example: 6 β†’ 24
    6 Γ— 4 = 24
  • To compare bigger to smaller β†’ Divide
    Example: 24 β†’ 6
    24 Γ· 4 = 6

βœ… If you multiply the smaller number and reach the bigger number β†’ Use β€œtimes as many”
❌ If multiplication doesn’t reach the number β†’ They are not multiples
