NUMBERS: Using the result of a known multiplicative fact to deduce the other not too dissimilar mathematical sums.
USING THE RESULT OF A KNOWN MULTIPLICATIVE FACT TO DEDUCE THE OTHER NOT TOO DISSIMILAR MATHEMATICAL SUMS.This is a way of working out a number by multiplying and dividing a number though the digits.
Here is a known question and answer...
37.4 x 7.15=267.41
EG1: 3.74 x 7.15= ?
So because the answer to the known fact is 267.41 and the question is 37.4 x 7.15 our example is 10 times smaller than it we will
divide the answer by 10.
267.41/10=
?=26.741
