Answer: 3 hours spent on homework in 5 days
Step-by-step explanation:
3/5 of an hour is 36 min.
Multiply 36 by the number of days he spent doing homework (5)
36x5=180 and 180 is equivalent to 3 hrs.
The equation is 20x = 1200
x=1200÷20
x=60 rows
Answer:
10% is equivalent to the unit fraction 23
To find 10% of 230, multiply 230 by 0.10
10% of 230 is 23
Think about it, if 100% of 230 is 230, and 10% is 23, you can multiply 23 x 100 to get 230. I took a while to answer, but I hope my explanation helps.
F(n) = 5n
You are being told n is the number of tables, and there are 15 tables:
f(15) = 5(15)
F(n) = 75
You need 75 candles.
