Answer:
see explanation
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)
Increase = 14
Total =50
Percentage increase = 14/50 x 100 = 28%
First we must change these numbers to improper fractions:
So then we set it up:
÷ 
When we divide fractions like this, we must flip the second fraction and change the sign from division to multiplication like so:
Then we solve:
Then if we divide the numerator and the denominator by 9, we get:
or, in mixed-number form, 
.
