66 jars of jam left after all the boxes are full
The 6 in 621 is in the hundred's place, so alone it would equal 600.
However, the 6 in 6,420 is in the thousand's place, so it alone would equal 6,000.
The question is asking how many times smaller is the value of 6 in these two numbers. Therefore, you need to divide 6,000 by 600.
Your answer should be 10.
X+x-x+y+y-z+z-z is equal to x+2y-z (combining like terms)
The answer is 40 square m
3/2 I'm pretty sure idk if I'm right though but you'll do good!
