Answer: what you need to do is multiply 3 times 1 and add 2 to the sum that you get which would be 5/3 for the first one because you keep the same denominator! Just multiply the denominator the bottom number and add the numerator the top number to your sum that you got from multiplication! Do that for all of them and you should get an improver fraction!

Finding the reciprocal is easy just flip the numbers I’m in 6th grade I learn this already!
to make mixed numbers into improper fractions, you multiply the whole number by the denominator, and add the numerator. you take that answer and make it the numerator in the new improper fraction, and keep the same denominator.
to take the reciprocal switch the numerator and the denominator.
use these to correct me if i messed up,, i couldn't see the numbers that clearly
Total-$31.23 explaination- you multiply 2.25 x4.8 and get 10.80 and then you multiply 2.25x7.3 and get16.43 then u add 4 to each of them and add them all up 14.80+16.43=31.23 and the 4 dollars are already included
