Find the greatest number that divides 36,45 and 63 without leaving a remainder

Step-by-step explanation:

I like to write out a multiplication of the lowest factors for each of the numbers and then compare them to find what might be the Greatest Common Factor.

Now,

36 = 2 × 2 × 3 × 3

45 = 3 × 3 × 5

63 = 3 × 3 × 7

∴ the GCF is 9.

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.
