How do I know if l -27 l in is less or greater than -45

If those two line on the side of -27 are there purposefully then they mean absolute value and so that would be positive 27 and on a number line the numbers to the right are greater than the ones on the left

So |-27| is GREATER than -45

7 weeks

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.
