With these, always write out the multiples first.
Start like this:
(assume one of the factors is negative)
1 and 1120
2 and 560
4 and 280
5 and 224
7 and 160
8 and 140
10 and 112
14 and 80
16 and 70
20 and 56
28 and 40
32 and 35
from those, the obvious choice is the one with a difference of three. In this case, 32 and 35, because -32 + 35 equals 3.
The lowest common denominator of the two fractions is 4 because it is the smallest number that both fractions can be transformed into. 3/2 is multiplied by 2 to create 6/4 which can be added to 11/4.
For every 2 things on the right, there will be 1 of the thing on the left exg
if there are 4 boys and 2 girls in a class the ratio is 4:2 or 2:1 (ratios can be simplified like fractions)
for every 2 boys, there is 1 girl,
You would get 2015.17568 as the interest rate i believe
