Step-by-step explanation:
(a)
= 1 ( any value divided by itself = 1 )
(b)
= a ( any value divide by 1 is the value itself )
(c)
× 
= 
The product of 2 fractions is the product of the numerators divided by the product of the denominators
(d)
÷ = 
To divide 2 fractions, leave the first fraction, change division to multiplication and turn the second fraction upside down, that is
÷ = × 
=
(e)
+ 
= 
Since the fractions have a like denominator, add the numerators leaving the denominator. This applies to subtraction also
(f)
- = 
See explanation for part (e)
Answer:
Maybe -12?
Step-by-step explanation:
Because sometimes variables on their own symbolize 1, so we can subtract 13 from 1 to get -12.
Since it is a square, the diagonals are congruent. If a square is split like this, it becomes two congruent right triangles. The relationship between the sides and hypotenuse is a 1:
ratio. So if the diagonal of a square is 14 cm, then the side length would be 14/
, which is approximately 9.899. I don't understand what the answer choices are, but you should be able to square root the numbers to determine the answer.
How about "miles per hour?" I drive "45 miles per hour" on my way into town.
That's a unit rate.
Did you know that 2 pints = 1 quart? You could write this rate / ratio as
2 pints
---------
1 qt
or as
(1/2 qt)
----------- this is a measure of one quantity per unit of another quantity.
1 pint
