B i cant really tell how because thats hard for me to do but it is b
What you do first is add the books 42 + 85 + 69 which equals 196. Then divide 196 by 7 and you get 28 :)
So for this it's asking to multiply 10,000 glass beads by the length of 0.4 cm.
So to make it easier let's just make it a fraction.
This will make it 4/10 (because 0.4 is just 4 tenths of a whole number)
So now we can upscale the sizes to the proper ratio. This ratio being the thousands.
4000/10000
Meaning the answer is 4000cm in length.
word form: one million, three thousand, four hundred ninety eight
number form : 1,003,498
expaned form 1000000 + 30000 + 400 + 90 + 8
i would so base form but i cant
In order they are
1.1 * 10^12, 9.5 * 10^11 and 5*10^8
