We know multiplication is repeated addition.Consider the following:(i) Andrea made sandwiches for 12 people. When they shared it equally, each of them got 1/2 a sandwich. How many sandwiches did Andrea make?
Repeated Addition:We know each people will get ½ a sandwich.
Multiplication:½ × 12 = 12/2= 6Therefore, Andrea made 6 sandwiches and shared with 12 people each of them got ½ a sandwich.(ii) Doreen then poured out a few bottles of fresh orange juice equally among the 8 people. Each of them got 3/4 of a glass. How many bottles of fresh orange juice did Andrea use?Repeated addition:
Multiplication: ¾× 8= 24/4= 6Doreen used 6 bottles of fresh orange juice.So, would you like to still continue adding or would you rather multiply.Since from the above examples, we can understand clearly that multiplication is faster.Related Links :● Multiplication is Repeated Addition.
