So, it depends on how many decimals are both numbers, but you wanna make sure that the divisor (is that what that called) is not a decimal.
so, if your question is 10.5 / 1.5,
you wanna make sure 1.5 is a whole number,
so you just change 1.5 into 15, by moving the decimal point to the back.
but this is unbalanced. so when you move the decimal point 1 step further, you wanna make sure the number youre dividing does it too.
so there you go, 105 / 15, and calculate that normally.
if your question is 15.015 / 1.5, you don't need to make 10.05 a while number, just make it to 150.15 / 15, as long 15 is a whole number, then ur fine. when you calculate that, follow the picture.
It would be C. he calculated the circumference of the earth.
A blanket
The sentence says, "I pulled the soft red wool over my <em>entire body</em>", so that means that the answer can't be a hat or a glove, you can't put a hat over your entire body. Since the sentence also uses "pulled", I can assume that the answer is blanket because I don't think that you commonly say, when wearing a sweater, that you pull it on.
