Which number has the greatest absolute value?
a. 18
b. –15
c. 7
d. –21

- D) -21

Step-by-step explanation:See when we consider absolute value, we don't consider the sign means we don't care about whether it is positive or negative.

We have to consider only it's magnitude.

And we know that amplitude of -21 is greater than amplitude of nos. given in other options.

So, D) is the correct option.

Hope it helps!!!

step-by-step explanation:

convert each fraction to the least common multiple of 20, so 3/4 = 15/20 & 1/10 = 2/20, then divide 15 by 2 and you get a little over 7, so the food will last 7 weeks.
