Almost 9 over 16 of the total water supplied to a household is used for taking showers. Determine the decimal equivalent of 9 over 16 . Use words to explain if the decimal terminates or repeats.

9/16 equals to 0.5625 so it terminates.

16 doesn't go into 9 so 0. Add a zero so 16 goes into 90 5 times and it equals to 80 so subtract 80 from 90 which equals 10.  Add another zero since 16 cant go into ten and 16 goes into 100 6 times and it equals to 96 so 100-96 equals 4. Sixteen cant go into 4 so add a zero which makes it 40. 16 goes into 40 2 times and it equals to 32 so 40-32=8. Add a zero to the eight and 16 goes into 80 5 times and etc etc.

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.
