Use rates, so 8 garden hoses over 18 hours
then find the how many hours one garden house can fill up by doing this = 18/8 you divide the 8 for both sides which is about 2.25/1
so then you times 9 which is about 20/9 hoses
your answer is 20

Your answer would be 20 because you have to take 18 and divide it by 8 and add the answer you get to the 18 hours and there’s your answer.

Over the weekend halverson had put together 3/16 if a jigsaw puzzle while jamie put together 10/16 of the puzzle. Who had coplet

Luden [163]

Answer:

Jamie. by 7/16

Step-by-step explanation:

Halverson completed: 3/16

Jamie completed: 10/16.

To understand who completed more, look at the denominator. The common denominator is 16. Assume a puzzle has 16 pieces and Halverson did 3 out of 16 and Jamie did 10 out of 16. This means Jamie did more.

If you want to know by how much Jamie did more, it would be the difference of both the fraction. This means that 10 done by Jamie minus 3 done by Halverson, which is 7. So 7 out of 16 is the difference.

$\frac{10}{16} -\frac{3}{16}$
