4,000*10= 40,000 which is forty thousands which is also 4 ten thousands
The value could also be 28 ones
25-7=18
18/25=x/100
the scale factor is 4
multiply 18*4
72%
(0.7p)=p-250
30% off of p must be equal to 250 less than p. As a result you can say that 0.7p (0.7Xp), which is 70% of p (100%-30%=70%) is equal to p-250, so 0.7p=p-250.
