Mathematics
1 answer:
Sergio [31]3 years ago
3 0

Answer:

Step-by-step explanation: Turn the mixed number into an improper fraction. -1 2/5 becomes -7/5.  To divide fractions, you keep the first fraction, change the division sign to mulitplication and flip the second fraction.  Then just multiply across the top and across the bottom. You will get 105/70.  Reduce by dividing both numerator and denomination by 35   Result will be 3/2.

On a scale drawing inch = 1 foot. What are the dimensions on the scale for a room that is 27 feet by 20 feet?
Rufina [12.5K]
If 1 inch = 1 foot then 1 foot = 1 inch.
With this, you can make a ratio of 1 foot:1 inch, or 1:1.
Starting with the first dimension, 27 feet, just change the 1 to 27 in the ratio.
27:?
To find how many inches this is in the scale drawing, find how much 1 had to be multiplied by to get to 27. This is 27, since anything times 1 is itself.
Just multiply the other side by 27 as well to get the answer for the first dimension.
1 • 27 = 27
So 27 feet = 27 inches in the scale drawing.
Now do the same for the second dimension.
1:1
20:?
1 • 20 = 20
20:20
The answer is that the scale drawing has dimensions of 27 inches by 20 inches if 1 inch = 1 foot is the scale

Alecsey [184]

Answer: blue= 93.625

Step-by-step explanation:

Let the red ball be y

Four times of red is 4y

And blue is seven times of red which means 7(4y)

4y+7(4y)=107

Open the bracket

4y+28y=107

32y=107

y=107/32

Make y the subject of formula

y=3.34

Therefore,blue is

7(4(3.34))

Blue= 93.625
