The area would be 21/50 since 7/10 times 3/5 is 21/50 and it cannot be simplified further therefore the area is 21/50 meters or 0.42 meters in decimal form
I will do #4. For dividing fractions, you multiply them together and remember to flip the second one.
Example: Instead of 2/5 divided by 3/4, it would be (2/5)(4/3), which = 8/15. Multiply the 2 and the 4 to get 8, then multiply the 5 and the 3 to get 15.
