Hi , you have to divide the numerator and the denominator , if you get a decimal you just have to move the period 2 spaces to the right.
For example
3/8 -0.375
0.375 - 37.5
408,017 is in standard form and
400,000+8,000+10+7=408,017 is expanded form
sixty five thousand and fifty eight is word form
60,000+5,000+50+8=65͵058 is expanded form
Well K is the sum of two integers so the product equals 2*11, as a Hero pointed out:
ac=2*11=22
k=sum of two integers so now it = to 22
I hope this helps :D
