When you divide a fraction by another fraction, it is the same thing as multiplying that fraction by its reciprocal.
The reciprocal is the 'flipped' version of a fraction where the numerator becomes the denominator and the denominator becomes the numerator.
for example, the reciprocal of 9/10 is 10/9
Knowing this information 4/5÷9/10 is the same as 4/5×10/9
Now we can solve...
Answer= 8/9
1 quart is equal to 4 cups, so 6.5 quarts are equal to? You have to multiply.
9/36 in the simplest form is 1/4
Answer: (C) 16
Step-by-step explanation:
Given : Number of sizes of self-stick notepads= 2
Number of colors = 4
Type 1 : The store packs the notepads in packages that contain 3 notepads of the same size.
i.e. By Fundamental principle of counting , we have
Number of different packages possible = Number of colors x No. of sizes
= 
Type 2: Notepads of the same size and of 3 different colors.
Choices for 3 different colors out of 4 : 
Again by fundamental principle :
Number of different packages possible = No. of choices for choosing 3 different colors x No. of sizes
=
From Type 1 and Type 2 , the total number of different packages of the types described above are possible =8+8= 16
Hence, the correct answer is option (c) 16.
14. Was the perimeter calculated correctly?
- Breadth = 1 *2/5 yards = 7/5 yards
We know that,
Perimeter of rectangle = 2 ( l + b )
= 2 ( 4 + 7 / 5 )
= 2 ( 20 + 7 / 5 )
= 2 × 27/5
= 54 / 5
= 1 * 4/5
No ...
