Question

Use the fa ct that 111=3times 37 to calculate a) 4times 3times 37 b) 37times 15

Answer 1

a)444 b)555

Answer 2

This question requires one to apply the knowledge of basic multiplication along with the given information that 111=3*37. For part a, we need to multiply the numbers 4,3 and 37 together. Taking into consideration the order of operations, the multiplication could also be performed by grouping 3 and 37 together first since their product is given, and finally multiply the result by 4 which simplifies our calculation. For part b, despite the fact that 15 isn't directly related to the provided equation, we can still utilize a simple trick often used in mental calculation. Break 15 down into 3*5 and we can hence apply the provided equation to multiplicand of 3*37, which is 111. Then multiply the result 111 by the remaining factor of 5. Doing it this way makes the computation feasibly simple.
