List from least to greatest 7/16 1/2 3/8 9/32 5/16 15/32
Ber [7]

There's a really simple way to answer this. Just like when you're adding fractions, you need to either turn them into decimals or make their denominators equal to put them in order

Here, we see the highest common denominator is 32, so we're going to turn all of the fractions' denominators into 32.

7/16=14/32

1/2=16/32

3/8=12/32

9/32=9/32

5/16=10/32

15/32=15/32

So, in order: 9/32, 5/16, 3/8, 7/16, 15/32, 1/2

olga55 [171]

Answer:

0.1 cents per ounce

Step-by-step explanation:

You know that you paid 88 cents for the whole bottle of ketchup and the whole body contains 9oz of ketchup. Every one ounce is equal to 9.8 cents. You simply need to divide the total amount of the item by the weight (9 ounces) to get 0.09 or 0.1 when rounded.

The force F between 2 objects is inversely proportional to the square of the distance, d between them. The force is 0.36 newtons
LenaWriter [7]

Answer:

0.73 N to 2 dp.

Step-by-step explanation:

F = k/d^2   where k is a constant , F = force and d = distance.

Substituting:

0.36 = k / (6)^2

k = 36*0.36 = 12.96 s the equation is F = 12.96 / d^2.

When d = 4.2 :

F = 12.96 / 4.2^2

F = 0.73 Newtons to 2 dp.
