Each day Jimmy feeds his horse 2.34 pounds of oats. He also feeds it hay. The weight of the hay is 3.5 time the weight of the oats. What is the combined weight of oats and hay that Jimmy feeds his horse in ONE week?

-66/22 to a decimal PLEASE I NEED THE ANSWER!!! I'LL MARK BRAINLIEST ​

Answers

Answer: -3

Step-by-step explanation:

Answer:

-3

Step-by-step explanation:

To turn a fraction into a decimal, all we need to do is divide the numerator by the denominator. But first, we can simplify! -66/22 simplifies to -3/1 when you divide by 22 on the top and bottom. Now, it's a lot easier to divide. -3/1=-3. -3 is technically already a decimal...you just can't see the decimal point. The decimal point is actually behind -3, so it looks like this: -3.0

Have a great day! Hope this helps!!! ^^
