By utilising the fact that subtraction is the reverse operation to addition. Thus, if A + B = C then C - B = A In this particular case, since 125 + 150 = 275 then 275 - 150 = 125
The GCF of 150 and 275 is 25. This leaves you with 6 and 11 respectively after division. There are no further factors that add to the GCF.
(100 + 150) ÷ 2 = 125 is the number in between.
Anything from 126 to 149 is between 125 and 150. The number exactly in between 125 and 150 is 137.5.
150 = 2 x 3 x 5 x 5 275 = 5 x 5 x 11
115 is halfway between 80 and 150
