Answer:
40%
Step-by-step explanation:
Percent is how much out of 100.
We have 2/5, so find equivalent fractions:
2/5 = 4/10 = 40/100
2/5 = 40%
Turn 7/4 into a decimal by dividing it and then multiply from there and you get 1.75. Then you time 5.4 by 1.75 and you get 9.45
This is what I found, I hope it helps! Good luck with your test
